Answer:
C. to explore the composition of Mars
Explanation:
Initially, in 2019, an unmanned mission is planned to orbit the moon. The spacecraft would flyby the moon. In 2020's, the Exploration Mission 2 would be a manned mission on the same path around the moon. This would be the base for future goal of collecting samples from mars. In later of 2020's unmanned spacecraft would be sent to mars and a robot would collect the samples from the Martian surface. In 2030's, a crew would be sent to Mars.
Answer:
One mole of carbon would look like 25/12.01
Explanation:
Firstly, you will divide 25 by 12.01 and get 2.081598
We know 1 mole equals the gram per atomic mass, so one mole of carbon is 12.01 grams. In conclusion, it would look like 25/12.01.
Glaciers capture large amount of carbon dioxide from atmosphere. When concentration of carbon dioxide molecules in glaciers increase, then strength and fracture toughness of ice are decreased and <span>that make glaciers vulnerable to cracking and splitting into fragments.
</span>That is because hydrogen bonds between water molecules in glaciers is decreased under increasing concentrations of carbon dioxide who <span>competes with the water molecules connected in the ice crystal.</span>
I think the answer you are looking for is .18 moles
Answer:
Double displacement reaction
Explanation:
Chemical equation:
H₃PO₄ + NaBr → HBr + Na₃PO₄
Balanced chemical equation:
H₃PO₄ + 3NaBr → 3HBr + Na₃PO₄
Step one:
H₃PO₄ + NaBr → HBr + Na₃PO₄
On left side of equation On right side pf equation
H = 3 H = 1
P = 1 P = 1
O = 4 O = 4
Na = 1 Na = 3
Br = 1 Br = 1
Step 2:
H₃PO₄ + NaBr → 3HBr + Na₃PO₄
On left side of equation On right side pf equation
H = 3 H = 3
P = 1 P = 1
O = 4 O = 4
Na = 1 Na = 3
Br = 1 Br = 3
Step 3:
H₃PO₄ + 3NaBr → 3HBr + Na₃PO₄
On left side of equation On right side pf equation
H = 3 H = 3
P = 1 P = 1
O = 4 O = 4
Na = 3 Na = 3
Br = 3 Br = 3
Type of chemical reaction:
The given reaction is double displacement reaction on which cation and anion of both reactants are replace with each other.
