Explanation:
The reaction expression is given as;
2H₂
+ O₂ → 2H₂O
From the balance reaction expression:
2 mole of hydrogen gas combines with 1 mole of oxygen gas on the reactant side;
This produces 2 mole of water on the product side of the expression.
The product is in liquid form.
This reaction is a synthesis reaction because a single product is formed from two reactants.
Answer:
A desinfecção
Explanation:
A desinfecção é o processo no qual o cloro é adicionado para matar microorganismos patogênicos prejudiciais, como bactérias, vírus, etc. Este é um processo químico e biológico. alguns desinfetantes comuns são cloro, dióxido de cloro e ozônio.
Answer:
B. control rods and moderators
Cl2 is nonpolar so it has to be only London dispersion force (LDF)
Answer:
Below
Explanation:
2) there are 28 protons in this isotope
The number that is on the bottom of the "stacked pair" tells you how many protons are in this isotope. It is often represented by the variable Z.
3) there are 35 neutrons in this isotope
Subtract the number of protons (28) from the top number
4) there are 28 electrons in the neutral element of Nickel
If you were to look at the period table and find Ni, you would see that its atomic number is 28. This number tells us the amount of protons and electrons there are in that element.
5) 62.9296694 atomic mass units
Just search it up (unless your teacher wants you to calculate it)
6) there are 92 protons in this isotope
Again just look at the Z value to find the proton count
7) there are 146 neutrons in this isotope
Subtract 238 - 92 = 146
8) there are 92 electrons in the neutral element of uranium
Again just look at the periodic table and find U
9) 238.0507882 atomic mass units
10) 12C or carbon 12 is more likely to bond with oxygen that 14c carbon 14
This is because 12C is more abundant at 98.93% than 14C
Hope this helps! Best of luck <3
