A substance is found to have a volume of 50 mL in an open beaker. In a flask, it changes
shape but maintains a volume of 50 mL. This substance is most likely:
A-Liquid
B-solid
C-gas
Answer:
LIQUID
Explanation:
The substance found to change shape in a different container but maintained volume is most likely a liquid.
STATE OF MATTER:Matter is any substance that has weight and occupies space. Matter can exist in three different states namely:
SolidLiquidGaseousLiquid as a state of matter is characterized by weak bonds that holds its particles together, hence, liquids flow.
Liquids assume the shape of the container that holds them. Hence, according to this question, the substance found to change shape in a different container but maintained volume (50ml) is most likely a liquid.

In science class, Blaine’s teacher puts one glow stick in a cup of hot water and another glow stick in a cup of cold water. She asks the students to think about how the temperature of the water will affect the chemical reaction that occurs inside the glow stick once it is bent and starts to glow.
Which glow stick will be brighter once it is bent? Explain your answer.
Answer:
The glow stick in hot water will be brighter
Explanation:
The glow stick in hot water will be brighter than the glow stick in cold water because the heat from the hot water will cause the molecules in the glow stick to move faster. The faster the molecules move in the glow stick, the sooner and brighter the reaction will be. The cold water will cause molecules to move slowly and it will take longer for the reaction to occur, which will also make it less bright.
Answer:
The glow stick that was in the cup of hot water will be brighter once it is bent. The production of more light is evidence that the chemical reaction in the glow stick is happening faster. The reaction happens faster, because increasing the temperature increases the rate of a chemical reaction.

Only genetic factors affect the growth of an organism.
Only environmental factors affect the growth of an organism.
Only environmental factors affect the growth of an organism.
The combination of genes and environmental factors affects the growth of an organism.
The combination of genes and environmental factors affects the growth of an organism.
Genes remove the environmental factors that affect the growth of an organism.
Genes remove the environmental factors that affect the growth of an organism.
Answer: The combination of genes and environmental factors affects the growth of an organism.
Explanation:
Gene consists of DNA and it's heredity physical and functional unit. Genes play a vital role in a organisms growth. For example in humans, if one's parents are tall, there's a large tendency that such child will be tall and vice versa.
Environmental temperature also affects growth of living organisms. These include water soil pH, temperature, gender, chemicals etc. These all affects growth, it should be noted that proteins in living organisms can be damaged at a certain temperature which invariably affects the growth of such organism.
Also, the environment influences gene expressions as temperature, light, drugs, and chemicals, affects genes as they determine which ones will either be turned on or off which will further lead to how such organism grows.

what are 3 examples of pairs of atoms with nonpolar covalent bonds?
Answer:
Carbon dioxide - CO.
Benzene - C6H.
Carbon tetrachloride - CCl.
Methane - CH.
Ethylene - C2H.
Explanation: Some examples of atoms with nonpolar convalent bonds. Hope this was found useful!!
Non polar covalent compounds have no net dipole moment due to charge separation. Some examples are, CO₂, H₂, N₂,O₂ etc.
What are covalent compounds?Covalent bonds are formed by the sharing electrons between atoms. Covalent bond is comparatively weaker than ionic bonds. Atoms of deficient number of electrons will combine by sharing their valence electrons and forms covalent bonds.
When one atom has more electronegativity, then the shared pair of electrons will attracted into the electronegative atom. This creates a charge separation and a dipole moment.
However, if the electronegative atoms are linear in geometry from the central less electronegative atom then the dipole moment cancel each other and the compound become non polar as in the case of CO₂.
All gases in molecular states are covalently bonded and are non polar such as H₂, N₂,O₂ etc.

what is balance equation and how we balance equation
Answer:
To adjust the substance condition, you need to ensure the quantity of molecules of every component on the reactant side is equivalent to the quantity of particles of every component on the item side. To make the two sides equivalent, you should duplicate the quantity of particles in every component until the two sides are equivalent.

How many grams of sugar must be dissolved in 150 mL of water to make a solution with a concentration of 0.6 g/mL?
Answer:
250
Explanation:
all you have to do is divide them its simple division cause its by the volume by the density
Mass can be calculated by using moles which can be further calculated from multiplication of Molarity to volume. The mass of sugar to make this solution is 8.6 kg.
What is molarity?
Molarity can be calculated by dividing number of moles of solute by volume of solution in litre. Molarity is affected by temperature. Its unit is mole/litre. It measure the concentration of any solute in a solution.
Other concentration terms are molality, normality and mole fraction. Molarity can be used to find out the ionic strength of any solution
Mathematically,
Molarity= number of moles of solute/volume of solution in litre
Where,
moles= given weight /by molecular weight
= w/ 96.0858
Substituting values in equation 1
0.6=(w/96.0858)/(150 )
w=8.6 kg
Thus the mass of sugar is 8.6 kg.

The process of water migrating from areas of low electrolyte concentration to area of high electrolyte concentration is called ———————. ——————— is the medicine term for the swelling of the brain
Answer:1-Diffusion
2-Cerebral edema
Explanation:
The process of water migrating from areas of low electrolyte concentration to areas of high electrolyte concentration is called diffusion.
Cerebral edema is the medical term for the swelling of the brain.
What is diffusion?Diffusion is a process where the substance or ions of from a low concentration to a high concentration. It occurs against the concentration gradient, so it needs energy.
Cerebral edema is a condition where fluid gets filled in the brain and the brain swells and make pressure on the skull called intracranial pressure.
Thus, Diffusion is the mechanism by which water moves from regions with low electrolyte concentrations to regions with high electrolyte concentrations.
The medical term for brain swelling is cerebral edema.
