Answer is: <span>D. 327,992.8 J.
</span>m(granite) = 17 kg = 17000g.
ΔT(granite) = 21°C - 45°C = -24°C (-24K).<span>
cp(granite</span>)
= 0,804 J/g·°C, <span>specific heat capacity of
granite.
Q = m(granite</span>) · ΔT(granite) · cp(granite).<span>
Q = 17000 g ·(-24</span>°C)<span>· 0,804 J/g·K.
Q = -327990 J.
</span>The granite lost 327990 joules of energy.<span>
Q - </span>amount of energy gained or lost.<span>
</span>
6 - one sodium atom, 1 hydrogen atom, 1 carbon atom, and 3 oxygen atoms.
<span>I think that the effective nuclear charge increases as you go up a group and across a period.
so maybe Rh, K, Ti, Mg, P
I hope I helped :)</span>
Answer:
3HC2H3O2(aq) + Al(OH)3(aq) --> AI(C2H3O2)3(aq) + 3H2O(l)
Explanation:
HC2H3O2 is the chemical formula for Ethanoic acid which can be written as CH3COOH.
Hence, the balanced equation is stated as 3CH3COOH(aq) + Al(OH)3(aq) --> AI(CH3COO)3(aq) + 3H2O(l)
Acid + base → Salt + Water.
The equation is a neutralization reaction in which the acid, aqeous CH3COOH reacts completely with an appropriate amount of base, aqueous Al(OH)3 to produce salt, aqueous AI(CH3COO)3(aq)
and water, liquid H2O only.
During this reaction, the hydrogen ion, H+, from the Ethanoic acid is neutralized by the hydroxide ion, OH-, from the Aluminum hydroxide to form the water molecule, H2O and aluminium ethanoate.
Thus, it is called a neutralization reaction.
A. Waves carry energy toward the energy source through space or through matter, and the matter moves with the energy
