Answer:

If volume remains the same while the mass of a substance <u>increases</u>, the density of the substance will <u>increase</u>.

Explanation:

Mathematically D = m/V tells us that density is directly proportional to the mass and inversely proportional to volume. Therefore if the mass increases the density will also increase.

Analytically, density is mass per unit of volume. So if you had 500 kg of mass packed in a one cubic meter box, clearly your density would 500 kg per cubic meter. Now if you added another 500 kg of mass in that same box(volume unchanged) the density goes up to 1000 kg per cubic meter. So If volume remains the same while the mass of a substance <u>increases</u>, the density of the substance will <u>increase</u>.

The Texas high plains region does not revive much rain. It is reasonable to predict that this region, compared to other ecoregio
mixas84 [53]

Answer:

Less soil erosion

Explanation:

Due to the low amount of rainfall in this region, it is easier to say that the region compared to other ecoregion will suffer less soil erosion.

Erosion is usually the washing away of the top layer of the soil. Rainfall is one of the most important element that causes erosion. Surface runoff for an extended period of time can remove the topmost layer of the earth on which plant can grow. This starves the soil of its rich nutrients and minerals.

The equilibrium expression for kp for the reaction below is __________. n2 (g) o2 (g) 2no (g)
PolarNik [594]
For the reaction;
N2(g) + O2(g) = 2NO(g)

Kp = pNO²/ pN₂pO₂; (No units)
where;
pNO is the partial pressure of NO;
pN₂ is the partial pressure of nitrogen
pO₂ is the partial pressure of Oxygen
The equilibrium constant  Kp is deduced from the balanced chemical equation for a reversible reaction, NOT experimental data as is the case for rate expressions in kinetics. 
Kp changes with temperature considerably changing the position of an equilibrium, and, at a constant temperature, and therefore constant K, the position of an equilibrium can change significantly depending on relative concentrations/pressures of 'reactants' and 'products'.

If you were helping a friend do stoichiometry problems, what would you tell them about how they might use subscripts and coeffic
Jet001 [13]
Im not sure if this will help but... your subscripts in a balanced equation are used to calculate the molar mass of the compound. And your coefficients are used to get the ratios. so for example we have this balanced equation
Be3N2 + 6H2O= 3Be(OH)2 + 2NH3  and you have to find the molar mass of 6h2o, you need to multiply the subscript by the atomic mass and then add them together to get the overall molar mass.  * 2(1.01) + 16.00= 18.02 g/mol
and if a question wants to know the limiting or excess regent you would use the coefficients to find out the ratio between the compounds.
