Determine la concentración de 10 ml de HCl que fueron valorados con 5 ml de NaOH 0.01 M. Seleccione una: a. 0.04 M b. 10 M c. 1 M d. 0.01 M e. 0.005 M
Answer:
0,005 M
Explanation:
Dado que:
Concentración de ácido (CA) = lo desconocido
Volumen de ácido (VB) = 10ml
concentración de base (CB) = 0.01 M
Volumen de base (VB) = 5 ml
Número de moles de ácido (NA) = 1
Número de moles de base (NB) = 1
Desde;
CAVA / CBVB = NA / NB
CAVANB = CBVBNA
CA = CBVBNA / VANB
CA = 0.01 × 5 × 1/10 × 1
CA = 0,005 M

Santiago's car has an overall average speed of 25 cm/s. If he could increase his car's overall average speed by 10%, what would his car's new overall average speed be?
Given:
The overall average speed = 25 cm/s.
The overall average speed increased by 10%.
To find:
The new overall average speed.
Solution:
We have,
Overall average speed = 25 cm/s.
The overall average speed increased by 10%. So, the new average speed is
New overall average speed = Initial average speed + 10% of initial overall average speed
[tex]\text{New overall average speed}=25+\dfrac{10}{100}\times 25[/tex]
[tex]\text{New overall average speed}=25+2.5[/tex]
[tex]\text{New overall average speed}=27.5[/tex]
Therefore, the new overall average speed is 27.5 cm/s.
Which of the following has more calories: table sugar or aspartame? Explain.
Answer: aspartame has more
Explanation: Aspartame contains 4 calories per gram (g), similar to sugar. It is, however, around 200 times sweeter than sugar. This means that only a tiny amount of aspartame is necessary to sweeten foods and drinks. so answer is aspartame
Aspartame has more calories. Why? Because aspartame manufactures four calorie kilograms of energy per gram when it's transfigured. Why is table sugar not the answer? Because table sugar manufactures 3.9 calorie kilograms. Also, aspartame is 200 times as sweet as table sugar, so it is eaten in much smaller portions. So your answer would be aspartame.

The seasons of the Earth are the result of --
a
the tilt of the Earth and its orbit around the Sun.
b
the Sun having a large gravitational pull.
c
the orbit of the moon around the Earth.
d
the continual rotation of the Earth on its tilted axis.
Answer:
the tilt of the Earth and its orbit around the Sun.
Explanation:
The seasons on the earth is as a result of the tilt of the earth and its orbit around the sun.
These phenomenon causes the four seasons of the earth. The earth is tilted at an angle of 23.5° from the perpendicular.
This causes the differences in yearly exposure of parts of the earth to solar radiation.
At some points, a part can experience very high insolation whereas it is low in other parts.
These variations results in the seasons on the earth.

Calculate the energy required to heat 622 g
mercury from 37°C to 42°C. The specific
heat capacity of Hg(l) is 0.138 J/g.° C.
Answer in units of cal.
Answer:
102.58 cal.
Explanation:
Given data:
Mass of mercury = 622 g
Initial temperature = 37°C
Final temperature = 42°C
Specific heat capacity of mercury = 0.138 J/g.°C
Energy required = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 42°C - 37°C
ΔT = 5°C
Q = 622 g × 0.138 J/g.°C × 5°C
Q = 429.18 J
J to cal:
429.18 J × 1 cal /4.184 j
102.58 cal.
what is the name of sc(oh)3
Answer:
Scandium(III) hydroxide
Explanation:
May I have brainliest please? :)
The name of the chemical compound Sc(OH)₃ is "scandium hydroxide."
A polyatomic ion is a charged chemical species composed of two or more atoms that are covalently bonded together and carry an overall electric charge. Unlike simple ions, which are single atoms with a positive or negative charge, polyatomic ions are groups of atoms with a net positive or negative charge due to the gain or loss of electrons.
In this compound:
"Sc" represents the chemical symbol for scandium, which is the metal cation in the compound.
"(OH)₃" represents three hydroxide ions (OH⁻) bound to the scandium cation.
The hydroxide ion (OH⁻) is a polyatomic ion that consists of one oxygen atom and one hydrogen atom, and it carries a negative charge.
So, the name of the compound Sc(OH)₃ is scandium hydroxide.

Why do clothes stick together when coming out of a dryer? And do the clothes start off as neutral?
here is what came up when i searched it up:
"The attraction between protons and electrons can also make clothes stick together in the dryer. When you dry clothes in the dryer, different fabrics rub together, and electrons from a cotton sock (for instance) may rub off onto a polyester shirt."
Sometimes, clothes can get stuck together after they come out of a dryer because of static electricity.
No, clothes may not start off as neutral. Whether clothes have static charges before going into the dryer depends on different things.
Why do clothes stick together when coming out of a dryer?Static electricity happens when certain things touch and create an uneven amount of electrons. This can cause one material to have a positive charge and the other to have a negative charge. When clothes move and touch each other in a dryer, this rubbing can cause static electricity.
If the clothes are cleaned and dried correctly, they should have no charge or be evenly charged.
