A hydrogen atom is number 1 on the periodic table so therefore a neutral hydrogen atom has 1 electron. since it’s mass is 1.00784 amu there is no neutron due to its size.
Answer:
2.1 x 10^6 J
Explanation:
Long story short, just think of the units of every question and then think again which unit needs to be cancelled out inorder for you to get the one which is asked.
the formula to calculate heat energy is Q = mcT
T - change in temperature
m - mass of substance
c - specific heat capacity of substance
the change in temperature is already given but you will need to change it to kelvin inorder for it to get cancelled out with the unit under specific heat capacity which is J/k gram. Tk = Tc + 273 = 3.32 + 273.15 = 276.47K
now keep in mind that c varies from substance to substance.
in this case it is 4.18J/k.g for water.
you will also need to convert the mass from kilograms to grams so it can cancel out as well. so now let's multiply 1.82 kg by a 1000 so that we can convert it to grams. which is equivalent to 1820g
now it's all set...let's substitute the values we dag out in the Heat formula Q = mcT
=1820g x 4.18Jk.g x 276.47K = 2.1 x 10^6J
so this is out final answer for heat required to raise the temperature of water by the particularly given quantity.
peace to you.
Answer:
The answer is Cycloheptanol
From the family pictures, people looked alike because they share similar genes.
<h3>What are genes?</h3>
Genes are units of inheritance located on the chromosomes which are passed on from parents to offspring. Members of a family look alike because of the genes that are passed on from parents to offspring.
Hence, from the family pictures, people looked alike because they share similar genes.
