<h3>
Answer:</h3>
1.265 g/mL
<h3>
Explanation:</h3>
<u>We are given;</u>
- Mass of a rock as 43 g
- Volume of the rock as 34 mL
- Altitude of the rock as 4390 ft
We are required to calculate the density of the rock.
Density is the mass of an object per unit volume.
It is calculated by;
Density = Mass / volume
Therefore;
Density = 43 g ÷ 34 mL
= 1.265 g/mL
Thus, the density of the rock is 1.265 g/mL
A-
From coefficients in the equation, for each mole of propane combusted, three moles of carbon dioxide molecules are produced. Thus
The question implied that the temperature and pressure on both carbon dioxide and propane are those under room conditions- so these values are supposed to be interchangeable; thus by the ideal gas equation
Answer:
Ammonium nitrate, (NH4NO3), a salt of ammonia and nitric acid, used widely in fertilizers and explosives. The commercial grade contains about 33.5 percent nitrogen, all of which is in forms utilizable by plants; it is the most common nitrogenous component of artificial fertilizers.
Answer:
heres the answer: Daily changes in the weather are due to winds and storms. Seasonal changes are due to the Earth revolving around the sun, differences in temperature create a restless movement of air and water in great swirling currents to distribute heat energy from the Sun across the planet.

if this is wrong i am genuinely sorry.
Answer:
180g
Explanation:
H:1 O:16
2H2+O2 → 2H2O
2 2(16) 2(1)+(16)
32 18
Now,
32g of O → 2(18)g of H2O
160g of O → 2(18)g divides by 32g times 160g
=180g
