Answer is: D. kilograms and cubic millimeters
.
Kilogram (symbol: kg) is the base unit of mass (anything that has mass in this question) in the International System of Units and cubic millimeter (symbol: mm³) is volume measurement unit (takes up space).
Second (symbol: s) is the base unit of time in the International System of Units and kilometer (symbol: km) is a unit of length in the metric system.
Gram (symbol: g) is a metric system unit of mass, but millimeter (abbreviated: mm) is an unit of distance in the metric system.
Yard (abbreviation: yd) is an unit of length and liter (symbol: l) is metric unit of capacity.
None because Covalent compounds don’t conduct electricity because they are formed between the non metal atoms by sharing of electrons. The Covalent compounds haves no free electrons and also no ions and hence they do not conduct electricity. That is why they do not conduct electricity.
Answer:
4+3=3+3+2
Explanation:
4Ni(oh)3+3pb(so4)2=3pb(oh)4+2Ni2(so4)3
Answer:
pH = 5.76
Explanation:
We can solve this problem by using<em> Henderson-Hasselbach's equation</em>:
pH = pKa + log![\frac{[SodiumAcetate]}{[AceticAcid]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BSodiumAcetate%5D%7D%7B%5BAceticAcid%5D%7D)
We are already know all the required information, thus we<u> input the data given by the problem</u>:
pH = 4.76 + log(20/2)
And finally <u>calculate the pH</u>:
pH = 5.76
The pH of that acetic acid solution is 5.76.
Explanation:
A catalyst has no effect on the equilibrium state, but it enables equilibrium to be reached more quickly by decreasing the “energy of activation”. In fact, a catalyst affects forward and reverse rates equally.
