Answer:
oxalate, fluoride, carbonate, phosphate.
Explanation:
It is important to consult the solubility chart in order to determine the anions.
Any compound with a low Ksp means the compound is very insoluble.
Hence, it means the formation of this compound is favoured strongly and its dissolution which would liberate calcium ions is unfavoured.
Any compound with a low Ksp would therefore "soak up" all the free calcium and will thus not be present in the solution.
Using solubility chart and noting the compounds with a low Ksp value, the anions that are probably present are: oxalate, fluoride, carbonate, phosphate.
Answer:
Water and Salt are the products of simplest types of acid-base reactions.
Examples:
Base Acid Salt Water
NaOH + HCl → NaCl + H₂O
2 NaOH + H₂SO₄ → Na₂SO₄ + 2 H₂O
NaOH + CH₃CO₂H → CH₃COONa + H₂O
In all theses simple reactions the base (i.e. OH⁻) abstracts proton from the acid and forming a conjugate base with negative charge. Thus the negative charged conjugate base forms a salt with positively charged sodium ions.
Answer:
C.) They have fewer electrons than protons
Explanation:
Charges on ions are determined by the ratio of electrons to protons. Neutral elements have the same number of protons and electrons. Remember: protons have a positive charge and electrons have a negative charge. However, based on the amount of electrons these elements have, some are more or less willing to give up their electrons to participate in ionic bonding. Potassium usually gives up 1 electron because this satisfies the octet rule. By removing this electron, the element has more protons than electrons, giving it an overall +1 charge.
The heat required to increase the temperature of 1.20 g of water is 80,256 k/j
<h3>What is specific heat?</h3>
The amount of energy needed to raise the temperature of one gram of a substance by one degree Celsius.
4. 18 J heat is required to change the temperature of 1.20 kg of water from 23. 00 °c to 39. 00 °c.
The heat required to raise temperature is the product of mass, specific heat and temperature change
1,200 × 4.18 × (39 − 23) = 80,256
Thus, the heat required to increase the temperature of 1.20 g of water is 80,256 k/j

It can reduce heat loss by heating water. Also plants are based on the dry process, and it’s much better for the environment rather than any other conventional process.
