Answer:
0.31 g
Explanation:
The equation of the reaction;
HKC8H4O4(aq) + NaOH(aq) ----> Na(KC8H4O4)(aq) + H2O(l)
Number of moles of NaOH = 15/1000 L × 0.1 M
= 0.0015 moles
Since the reaction is 1:1, 0.0015 moles of KHP reacted;
Number of moles of KHP = mass of KHP reacted/molar mass of KHP
Mass of KHP = Number of moles of KHP × molar mass of KHP
Mass of KHP = 0.0015 moles × 204.22 g/mol
Mass of KHP = 0.31 g
This would be the downward movement of water. It begins flowing and continues in a downward movement moving throughout,
Putting solar panels on houses is a great idea, for it provides a renewable source of energy and heat, which is the sun. It will help prevent pollution and the mass-use of non-renewable resources, such as fossil fuels, which are used and burned for energy.
Although, having solar panels, there will be some downsides. For example, solar panels can only receive energy during time where there is light from the sun, which is daylight. therefore, the solar panels will not and cannot be able to collect energy from the sun during night time. although, depending on the solar panels, some can store energy, from the sun, that can be used at night time, like as if you're charging a battery with energy from the sun for later use. one big problem is that, solar panels are not cheap and rather quite expensive, which not all homes and families can afford. although, through time, solar panels will get cheaper.
but, all in all, I believe that solar panels give a great contribution to Earth, thus I agree to the use of solar panels.
Answer:
I guess the answer is D point
Answer:
Explanation:
According to octet rule there should be 8 electrons in the atom's subshell/valence shell. Giving it the same electronic configuration as a noble gas.
among the options:
c) option is correct, as 5 bonds to carbon is violating the octet Rule, 5 bonds means 10 electrons exceeding the noble gas configuration and violets the octet rule.
All the other options are are incorrect, they are following
octet rule. Three bonds of carbon is possible in the case of carbocation.
