An object has a weight of 5.10 Newtons (N) at sea level, where the acceleration due to gravity is 9.81 m/s2.
RUDIKE [14]
Well, you could get the mass as m=\frac{G_0}{g_0} ad then g_1=\frac{G_1}{m}, where G_0 is the sea level weight, g_0 the sea level accel., g_1 the accel. above while G_1 the weight above.

Why does the fact that Americans are using less fertilizer not indicate a decline in American farming?
meriva
It shows that the population is moving towards a more organic and natural way of growing crops. Rather than using fertilizer and putting toxins on the plants that we eat from, we are getting smarter and growing food naturally. Thus not killing ourselves in the process.

Find the weight of HNO_3 present in 20ml, 0.30 N
yanalaym [24]

Answer:

mass of HNO₃ = 0.378 g

Explanation:

Normality = Molarity * number of equivalents

Molarity = Normality/number of equivalents

normality of HNO₃ = 0.30 N, Volume = 20 mL

HNO₃ ionizes in the following way:

HNO₃(aq) ----> H⁺ + NO₃⁻

Therefore, number of equivalents for HNO₃ is 1

molarity of HNO₃ = 0.30/1 =0.30 mol/dm³

Using the formula, molarity = number of moles/volume in liters

number of moles = molarity * volume

Number of moles of HNO₃ = 0.30 mol/dm³ * 20ml * 1 dm³ /1000 mL

number of moles = 0.006 moles

From the formula, mass = number of moles * molar mass

molar mass of HNO₃ = 63.0 g/mol

mass = 0.006 * 63

mass of HNO₃ = 0.378 g

Why is it important for the pH of blood to remain constant?
lesya692 [45]
It is important for the pH of blood to remain constant because your blood would ionize and burn up if the pH wasn't constant. And if the pH was too high, bacteria ( good and bad, and foreign) would end up dying, as well as yourself.
