Answer:
You get Ca(II)H^2
Explanation:
This is a reaction type equation calcium reacts with HA and forms a bond.
Balanced chemical reaction:
2HNO₃<span>(aq) + Sr(OH)</span>₂(aq) → 2H₂O(l) + Sr(NO₃)₂<span>(aq).
Balanced ionic reaction:
2H</span>⁺(aq) + 2NO₃⁻(aq) + Sr²⁺(aq) + 2OH⁻(aq) → 2H₂O(l) + Sr²⁺(aq) + 2NO₃⁻(aq).
Net ionic reaction:
2H⁺(aq) + 2OH⁻(aq) → 2H₂O(l).
(aq) means that substances are dissociated on cations and anions in water.
The mass of carbon in 1 liter of mixture = 1.108 g
<h3>What is the mass of carbon in 1 liter of the mixture?</h3>
The mass of carbon in 1 liter of the mixture is determined as follows:
First the moles of gas is determined using the ideal gas formula:
n = (1 * 1)/(0.08205L * 298)
n = 0.0409 mole of total gas
mass of gas is then determined using the formula:
mass = 1 * 1.375
mass = 1.375 g
Let x = mass of CH₄ and y = mass of C₄H₁₀
x + y = 1.375 g
nCH₄ + nC₄H₁₀ = ntotat
moles = mass/molar mass
x + y = 1.695 => y = 1.695 - x
(x/molar mass of CH₄) + [(1.375 - x)/ molar mass C₄H₁₀ = 0.0409
x/16 + (1.375 - x)/58 = 0.0409
x = 0.380 g CH₄
y = 1.375 - 0.380
y = 0.995 g of C₄H₁₀
mass of C in CH₄ = 12/16 * 0.380 = 0.285
mass of C in C₄H₁₀ = 48/58 * 0.995 = 0.823
Mass of carbon in 1 liter of mixture = 0.285 + 0.823
Mass of carbon in 1 liter of mixture = 1.108 g
In conclusion, the carbon is the major component in the mixture.

<span>In general,atomic size increases from top to bottom within a group and decreases from left to right across a period</span>
Answer:
Option (C)
Explanation:
Atoms are the basic structures that are combined to form minerals, which are further accumulated giving rise to the formation of rocks. These atoms plays a significant role in the formation of rock and their significant characteristics.
When atoms are passed through the rock cycle, they are not able to move at the same rate, but they can move at a different rate. When a rock changes from one kind to another, its constituent minerals and atoms also alters, forming a different rock type with variable characteristics and properties.
Thus, the correct answer is option (C).
