Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.

What happens to the average kinetic energy at a constant temperature? *
1.it increases
2.it decreases
3.it stays the same
4.it disappears
Answers
As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container. The force exerted by the particles per unit of area on the container is the pressure, so as the temperature increases the pressure must also increase.
If the temperature of a gas in a balloon remains constant but the pressure
is decreased, the volume of the balloon will
decrease
increase
remain the same

Answers
Answer:
increase
Explanation:
if the pressure goes down then the gas will spread out more, meaning the volume will increase

The term mole is defined as the amount of substance of a system which contains as many elementary entities. A mole of Br₂ and a mole of CH₂Br₂ have a mass of 1g each. Therefore, option A is correct.
What do you mean by mole ?The term mole is defined as the amount of substance of a system which contains as many elementary entities.
1 mole is equal to 6.023 × 10 ²³ molecules.
One mole of any substance is equal to 6.023 × 10²³ units of that substance such as atoms, molecules, or ions. The number 6.023 × 10²³ is called as Avogadro's number or Avogadro's constant.
The mole concept can be used to convert between mass and number of particles.
A mole of Br₂ and a mole of CH₂Br₂ have a mass of 1g each. Because one mole of substance is equal to 6.023 × 10 ²³ molecules.
Thus, option A is correct.

If 23.17 g of beryllium (Be) reacts with water at standard temperature and pressure,
how many liters of hydrogen (H2) are produced?
Answers
Volume of H2 produced = 57.6576 L
Further explanationGiven
23.17 g Be
Required
Volume of H2
Solution
Reaction
Be(s)+H2O(g)→BeO(s)+H2(g)
mol Be :
= 23.17 g : 9 g/mol
= 2.574
From the equation, mol H2 : mol Be = 1 : 1, so mol H2 = 2.574
Volume H2(assumed at STP, 1 mol=22.4 L) :
= 2.574 x 22.4 L
= 57.6576 L

In the equation CH4 + 2O2 --> 2H2O + CO2 What is the mass of CO2 produced when 35g of O2 reacts?
Answers
Answer:
24.06 g of CO₂
Explanation:
The balanced equation for the reaction is given below:
CH₄ + 2O₂ —> 2H₂O + CO₂
Next, we shall determine the mass of O₂ that reacted and the mass of CO₂ produced from the balanced equation. This can be obtained as follow:
Molar mass of O₂ = 2 × 16 = 32 g/mol
Mass of O₂ from the balanced equation = 2 × 32 = 64 g
Molar mass of CO₂ = 12 + (2×16)
= 12 + 32
= 44 g/mol
Mass of CO₂ from the balanced equation = 1 × 44 = 44 g
SUMMARY:
From the balanced equation above,
64 g of O₂ reacted to produce 44 g of CO₂.
Finally, we shall determine the mass of CO₂ produced by the reaction of 35 g of O₂. This can be obtained as follow:
From the balanced equation above,
64 g of O₂ reacted to produce 44 g of CO₂.
Therefore, 35 g of O₂ will react to produce = (35 × 44)/64 = 24.06 g of CO₂.
Thus, 24.06 g of CO₂ were produced from the reaction.

54 grams
b 40 grams
C
30 grams
d 20 grams
Answers
Answer:
[tex]\boxed {\boxed {\sf A. \ 54 \ grams }}[/tex]
Explanation:
To convert from moles to grams, we must use the molar mass.
Recall that water's molecular formula is H₂O. It contains hydrogen and oxygen. Look up the two elements masses on the Periodic Table.
Hydrogen (H): 1.008 g/mol Oxygen (O): 15.999 g/molNow, use these masses to find water's mass. The subscript of 2 tells us there are 2 atoms of hydrogen, so we multiply hydrogen's mass by 2 and add oxygen's.
H₂O= 2(1.008 g/mol) + 15.999 g/mol = 18.015 g/molUse the molar mass as a ratio.
[tex]\frac{18.015 \ g \ H_2 O}{ 1 \ mol \ H_2 O}[/tex]
Multiply by the given number of moles.
[tex]3 \ mol \ H_2O*\frac{18.015 \ g \ H_2 O}{ 1 \ mol \ H_2 O}[/tex]
The moles of water will cancel.
[tex]3 *\frac{18.015 \ g \ H_2 O}{ 1 }[/tex]
[tex]3 *{18.015 \ g \ H_2 O}[/tex]
[tex]54.045 \ g \ H_2O[/tex]
Round to the nearest whole number. The 0 in the tenth place tells us to leave the number as is.
[tex]54 \ g \ H_2O[/tex]
There are about 54 grams of water in 3 moles.
Answer:
54 grams
Explanation:
First step is to find what one mole of water is in grams.
Water is H2O so that means we have two moles of Hydrogen.
H - 2 grams (on periodic table)
We have one mole of Oxygen.
O - 16 grams (on periodic table)
Add 2 and 16 to get 18 total grams in one molecule of H2O
Now multiply 3 times 18 to know how many grams in 3 moles of H2O
You end with
3x18=54 grams
