Question: <span>How many grams of Nickel are in 1.57 moles of nickel
There are 58.6934 grams of Nickel in 1 mole.
There are 92.1486 grams of Nickel in 1.57 moles.
Nickle is the most common ore to find on Earth. The atomic number of Nickle is 28 and the symbol for Nickle is Ni. The color is silvery-white with a tinge of gold.
Final Answer:
</span>
There are 92.1486 grams of Nickel in 1.57 moles.
Answer is: H₂PO₄⁻ (d<span>ihydrogen phosphate).
Chemical reaction: HPO</span>₄²⁻(aq) + H⁺(aq) ⇄ H₂PO₄⁻(aq).
According to Bronsted-Lowry
theory acid are donor of protons and bases are acceptors of protons (the
hydrogen cation or H⁺). Hydrogen phosphate is Bronsted base and it can accept proton and become conjugate acid.
Answer:
D. Solid state
Explanation:
In solid state the particles of a substance, vibrate in fixed positions though they posses less kinetic energy. This is the reason as to why the particles do not move far apart from each other making the solids remain in fixed shapes unless an extra energy is added.
The total quantity of heat evolved in converting the steam to ice is determined as -12,928.68 J.
<h3>
Heat evolved in converting the steam to ice</h3>
The total heat evolved is calculated as follows;
Q(tot) = Q1(steam to boiling point) + Q2(boiling point to ice) +Q3(freezing to -42 ⁰C)
where;
Q = = mcΔθ
where;
- m is mass, (mass of water = 18 g/mol)
- c is specific heat capacity,
- Δθ is change in temperature
Q(tot) = 2(18)(2.01)(100 - 135) + 2(18)(2.01)(0 - 100) + 2(18)(2.09)(-42 - 0)
Q(tot) = -12,928.68 J
Thus, the total quantity of heat evolved in converting the steam to ice is determined as -12,928.68 J.
