Answer:
C(s) + H2O(g) → CO(g) + H2(g)
Explanation:
Carbon monoxide and hydrogen. Possibly some reaction products from impurities in the coke, but mostly CO and H2.
Answer: 1618.8g of Zinc
Explanation:
We begin by writing a balanced chemical equation for the reaction.
Zn (s) + H2SO4 (aq) ----------> ZnSO4 (aq) + H2 (g)
Atomic mass of Zinc is 65.4g/mol
Molecular mass of hydrogen gas is 2.02 g/mol
Looking at the balanced equation;
2.02g is produced by 65.4g of Zn
50g would be produced by 65.4÷ 2.02 x 50 = 1618.8g of Zinc
<u>Answer:</u>
<em>The mole to mole ratio between oxygen gas and water is 2 : 1</em>
<em></em>
<u>Explanation:</u>
Balancing is making the number of atoms of each element same on both the sides (reactant and product side).
To find the number of atoms of each element we multiply coefficient and the subscript
For example
contains
5 × 1 = 5 ,Ca atoms and
5 × 2 = 10, Cl atoms
If there is a bracket in the chemical formula
For example
we multiply coefficient × subscript × number outside the bracket to find the number of atoms
(Please note: 3 is the coefficient, and if there is no number given then 1 will be the coefficient )
So
3 × 3 = 9 , Ca atoms
3 × 1 × 2 = 6, P atoms
3 × 4 × 2 = 24, O atoms are present.
So
The balanced chemical equation is
The number which stands in front of the chemical formula is the coefficient and it represents the number of moles of each substance.
So we see here 2 is the coefficient of and 1 is the coefficient of
So the mole ratio of water and oxygen gas is 2 : 1
(Answer)
Answer:
Electrons repel each other due to electrostatic force of attraction between both of them as a result prevent the electron from entering the nucleus preventing it from collapsing
Answer:
e. Na, Fe, K
Explanation:
The group of elements that will be positive charge ions is metal. You can find metal in the first 2 columns of the periodic table and in the transition area. Natrium/sodium (Na), iron (Fe), and kalium/potassium(K) categorized as metal and they will form positive charge ions.
On the other hand carbon(C), oxygen (O), arsenic(As) and bromine(Br) is gas and will form negative charge ions. Gas located on the right side of the periodic table.
