Regulates the volume and pH of the internal environment. The human excretory system maintains homeostasis by removing metabolic waste such as water, salt and metabolite concentrations in the blood.
Answer:
Hypercalcemia can cause stomach upset, nausea, vomiting and constipation. Bones and muscles. In most cases, the excess calcium in your blood was leached from your bones, which weakens them. This can cause bone pain and muscle weakness.
Some symptoms are:
Fatigue, bone pain, headaches.
Nausea, vomiting, constipation, decrease in appetite.
Forgetfulness.
Lethargy, depression, memory loss or irritability.
Muscle aches, weakness, cramping and/or twitches.
Answer:
3.785411784
Explanation:1 gallon (gal) = 3.785411784 kilogram (kg). Gallon (gal) is a unit of Volume used in Standard system. Kilogram (kg) is a unit of Weight used in Metric system. Please note this is volume to weight conversion, this conversion is valid only for pure water at temperature 4 °C.
US oz = 28.349523125 g
US fl oz = 29.5735295625 ml (milliliters) = 29.5735295625 g (grams) of pure water at temperature 4 °C.
US cup = 8 fl oz = 236.5882365 ml (milliliters) = 236.5882365 g (grams) of pure water at temperature 4 °C.
The US gallon is equal to 3.785411784 liters and defined as 231 cubic inches. Kilograms also can be marked as kilogrammes in UK.
Answer:
C. 7 is the pH scale of water.
Answer:
In calcium oxide (CaO), oxygen and calcium are respectively a non-metal and a metal, whose bonding is based on the exchange of electrons to form an ionic bond, which balances their charges and makes it chemically stable.
Explanation:
<em>What is the reason that in the calcium oxide molecule is caO and not Ca₂O or CaO₂?</em>
Calcium is a metallic element -a soft metal- that is capable of bonding with a non-metallic element such as oxygen to form an ionic bond, so that each Ca atom will bond to a single O atom.
CaO (calcium oxide)
- <em>Ca Z = 20 </em>
- <em>O Z = 8</em>
Ca + O ---→ Ca⁺² + O ⁻²
K L M N K L K L M K L
2 8 8 2 2 6 2 8 8 2 8
The electron exchange that is observed occurs between +atom and atom, and for this reason the chemical formula of calcium oxide is CaO.
Calcium oxide (lime) is obtained by heating calcium carbonate (CaCO₃) to very high temperatures through the following reaction
CaCO₃ + heat → CaO + CO₂
