What effect does heat have on a chemical reaction?
Answers
Answer:
Particles can only react when they collide. If you heat a substance, the particles move faster and so collide more frequently. That will speed up the rate of reaction. ... The rate of reaction will probably have doubled for that increase in temperature - in other words, an increase of about 100%.

The chemical formula for hydrogen peroxide is H2O2. What is the total number of atoms in 1 molecule of hydrogen peroxide?
Answers
Answer:
THE TOTAL NUMBER OF ATOMS IN 1 MOLECULE OF HYDROGEN PEROXIDE ARE 4 ATOMS.Explanation: 1 molecule of hydrogen peroxide contains 2 hydrogen atoms and 2 oxygen atoms.I HOPE THAT THIS ANSWER HELPS YOUThe chemical formula for hydrogen peroxide is H₂O₂. The total number of atoms in 1 molecule of hydrogen peroxide is four atoms. Two atoms of hydrogen and two atoms of oxygen.
What is hydrogen peroxide ?Chemically, hydrogen peroxide has the formula H₂O₂. It is a somewhat more viscous liquid than water, and very pale blue when it is pure. For consumer use, it is typically diluted in water and used as an oxidant, bleaching agent, and antiseptic. For industrial use, larger concentrations are utilized.
Hair bleaching, surface cleaning, and tool disinfection are all done using hydrogen peroxide. It is also utilized in gardening and dental hygiene.
Two hydrogen and two oxygen atoms make up one molecule of H₂O₂. Therefore, two molecules of H2O2 contain four hydrogen and four oxygen atoms each. Two hydrogen atoms and one oxygen atom make up a water molecule.
Thus, The total number of atoms in 1 molecule of hydrogen peroxide is four atoms.

A cube has a mass of 9 grams and each side is 3 cm3. What is the density of the sample?
a.0.33 g/mL
b.36g/mL
c.3g/mLd.18g/mL
Im begging someone to help, Ill mark brainlist!!!
Answers
Answer:
a. 0.33 g/mL
Explanation:
We already know what the mass is (9 grams) so we have to find the volume of the cube next.
Volume = lwh
=(3)(3(3)
= 27
To find density, you have to find mass/volume
density = mass /volume
density = 9 g /27 mL (cm 3 and mL are basically the same thing)
= 0.33 g/mL
