The compound HNO3 is called nitric acid.
HNO3 is a covalent compound and a strong acid which ionizes in water into H+ (proton) and NO3- (nitrate ion).
HNO3 (aq) ↔ H+(aq) + NO3-(aq)
Ans: HNO3 = Nitric Acid
[On a side note: Nitrous acid is HNO2]
The barometer would show a decrease in wind speed resulting in the disipation of cloud cover because of the lack of wind, and also because the temperature is dropping there is less precipation because there is no hot air rising to create clouds :)
every action of has an opposite and equal reaction so we know that the rifle moved back toward her shoulder because the bullet that was fired out of gun was moving at a very high speed.
Answer:
3120.75J
Explanation:
So, we have the formula 
. For this example, q is the heat energy in Joules, m is the mass in grams, c is the specific heat capacity in 
, and 
t is the change in temperature. In this case, m = 47.5g, c = 0.9 , and t = 94-21 = 73°C. Plugging in the values, we get the joules of heat required to raise 47.5g of Al from 21°C to 94°C which is stated above. You can double check my answer but that should be it. An important thing to be aware of are the units. Sometimes, the heat capacity may not be . I may be in Kelvin or something. Anyways, hope this helps.
Answer:
2.1 M
Explanation:
Molarity is moles per liter:
0.512 mol NaCl / 0.24 L = 2.1 M
