Mg + 2HCl → MgCl2 + H2
How many grams of hydrochloric acid (HCI) is needed to produce 200g of H2?
Answers
Answer:
7242.1g
Explanation:
The balanced equation for this reaction is as follows:
Mg + 2HCl → MgCl2 + H2
From the above equation, it can be observed that 2 moles of HCl is needed to produce 1 mole of H2.
Using the formula below, we convert the mass of H2 to moles;
Molar mass of H2 = 2.016g/mol
mole = 200/2.016
mole = 99.21mol of H2
Since 2 moles of HCl is needed to produce 1 mole of H2.
Then 99.21 moles of H2 will be produced by 99.21 × 2 = 198.4mol of HCl
Molar mass of HCl = 1 + 35.5
= 36.5g/mol
Mole = mass/molar mass
Mass = molar mass × mole
Mass = 36.5 × 198.4
Mass = 7242.1g

(PLEASE HELP) 500 mL of a gas is collected at 745 mmHg. What will the volume be at 1.8 atm?
Answers
Answer:
272.22 mLExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we're finding the new volume we have
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
First convert 745 mmHg to atm
760 mmHg = 1 atm
745 mmHg = 745/760 = 0.98 atm
We have
[tex]V_2 = \frac{500 \times 0.98}{1.8} \\ = 272.222...[/tex]
We have the final answer as
272.22 mLHope this helps you

Suppose that decades of overfishing in the Atlantic Ocean have led to a large decrease in the Atlantic cod population. As a result, there has been a steady decrease in the number of other predator species in the ecosystem. All of the populations in this marine ecosystem are now in danger of decline because of this imbalance.
Which of the following solutions would best help preserve the biodiversity of this ecosystem?
A.
introducing non-native fish species that can repopulate the ecosystem if the native populations continue to decline
B.
only allowing commercial fishing companies to fish for predator fish in this ecosystem for the next several decades

MARKING BRAINLIEST Think about the fact that water is most dense at 4°C, and the fact that ice is much less dense than
water.
a. What would happen to a lake or a pond in the winter (in a cold climate) if this wasn’t the
case?
b. What if the water continued to contract, and the solid form (ice) was more dense than liquid
water?
c. How would this affect the life in the lake
please answer all
Answers
Answer:
See Explanation
Explanation:
a) If water is not most dense at 4°C, then the entire lake or pond will simply freeze bottom-up during winter thereby leading to the death of all the aquatic organisms inside the pond.
b) If the solid ice was more dense than water then it will sink inside the water thereby making room for the water to continue to freeze until all the water in the lake or pond will be converted to ice.
c) If the scenario described in (a) and (b) above occurs, the lake will simply cease to exist because all the living organisms in it will die and begin to decay after the ice has melted after the winter season thereby leading to a complete loss of the lake or pond.

You have a mixture that contains 0.380 moles of Ne(g), 0.250 moles of He(g), and 0.500 moles CH4(g) at 400 K and 6.25 atm. What is the partial pressure of He?
Answers
Answer:
1.38 atm
Explanation:
Partial pressure of a gas = total pressure × mole fraction of that gas.
Mole fraction of a gas is moles of a gas ÷ total moles of all gases.
The partial pressure of Helium gas is 2.756 atm. This can be calculated by using mol fraction first.
Calculation of mol fraction:
It is the ratio of one mole of gas to the total moles of all the gases.
Total moles of all gases = 0.380+0.250+0.500 =1.13
Mol fraction of Helium gas = 0.500/1.13
Mol fraction of Helium gas = 0.442
Calculation of partial pressure:It is the product of mol fraction of the gas to the total pressure given.
Partial pressure= 0.442 * 6.52 atm
Partial pressure=2.765 atm

18.) CCC Energy and Matter Photovoltaic power from solar panels and biomass
energy are obviously forms of solar energy, coming from sunlight. Explain why
both wind power and hydroelectric power can also be considered to be forms of
solar energy.
Answers
Answer:
See Explanation
Explanation:
Renewable energy sources refers to those energy sources that can never be depleted. This means that they can be used severally without getting exhausted. Solar, biomass, wind and hydroelectric power are all renewable energy sources.
Hence, from the perspective described above, we can say that wind is a form of solar energy because wind is formed when the air is heated by the sun.
Hydroelectric power is driven by the water cycle. This water cycle somehow depends on the sun to run efficiently. So, hydroelectric power can also be considered to be a form of solar energy.

what volume of hydrogen at STP would be
produced?
1. 9.68 liters
2. 10.60 liters
3. 4.84 liters
4. 19.37 liters
5. 22.40 liters
Answers
Solution,
Mass of Mg - 21gm
molar mass of Mg - 24gm
moles = Given mass/ Molar mass
moles = 21/24 = 0.875
1 mole of Mg produce 1 mole of H2 gas
so 0.875 mole of Mg will produce 0.875 moles of H2 gas
One mole of H2 gas = 22.4 litre
0.875 mole of H2 gas = 0.875×22.4
0.875 mole of H2 gas = 19.60 litre
So the nearest ANSWER is Option four 19.37 litre.
STP is the standard temperature and the pressure of the gases of the system. The volume of the hydrogen that will be produced as STP is 19.37 litres.
What is volume?Volume is the amount of the substance or the solution occupied in an area or object and is estimated in L or mL. It is a scalar quantity.
Given,
Mass of magnesium = 21 gm
Molar mass of magnesium = 24 gm/mol
Moles of magnesium can be calculated as,
[tex]\begin{aligned}\rm moles &= \rm \dfrac{mass}{molar\;mass}\\\\&= \dfrac{21}{24}\\\\&= 0.875 \;\rm mol\end{aligned}[/tex]
If 1-mole magnesium = 1-mole hydrogen gas
Then 0.875-mole magnesium = 0.875 moles of hydrogen gas
If 1 mole of hydrogen gas = 22.4 L
Then, 0.875 moles of hydrogen gas = x L
Solving for x:
[tex]\begin{aligned}\rm x &= 0.875 \times 22.4\\\\&= 19.60 \;\rm litre\end {aligned}[/tex]
Therefore, the volume of hydrogen at STP would be option 4. 19.37 litres.

A student added 3 gms one substance in a beaker and then added 4 gms of another substance. A chemical reaction took place in the uncovered beaker, after the reaction the beaker weighed 5 gms which of the following is the best explanation?
A Some of the mass of the reactants was lost as heat and evaporated into the air.
B. The reaction produce a gas as a product.
C. Some of the reactantants were destroyed as when the chemicals were added.
Answers
Answer:
B. The reaction produce a gas as a product.
Explanation:
According to the law of conservation of mass, the total mass of reactants must be equal to the total mass of products because mass is neither created nor destroyed in a chemical reaction.
The total mass of the reactants is 7 grams. The total mass of the products and the beaker is 5 grams. This means that the mass of products is less than the mass of reactants.
The only plausible explanation for this is that the reaction produced a gaseous product which escaped because the system is an open system thereby leading to a lesser measured mass of products since mass can not be created nor destroyed.
