Tha is really easy just search them all up ,but ill get u started
In which season is the sun closest to the earth?Answer Summer
Answer:
14.33 g
Explanation:
Solve this problem based on the stoichiometry of the reaction.
To do that we need the molecular weight of the masses involved and then calculate the number of moles, find the limiting reagent and finally calculate the mass of AgCl.
2 AgNO₃ + CaCl₂ ⇒ Ca(NO₃)₂ + 2 AgCl
mass, g 6.97 6.39 ?
MW ,g/mol 169.87 110.98 143.32
mol =m/MW 0.10 0.06 0.10
From the table above AgNO₃ is the limiting reagent and we will produce 0.10 mol AgCl which is a mass :
0.10 mol x 143.32 g/mol = 14.33 g
Answer:
vinegar is acidic
water should be neutral but people say since it's pH 7,it will be more alkaline
salt solution is acidic
lemon juice is acidic
sugar solution is alkaline
soap is alkaline
Methyl orange will turn red with grapefruit juice.
Methyl orange will turn yellowish orange or lemme say red with oven cleaner
The addition of pure water to methyl orange will not have an effect on the color and the solution will still be around neutral pH and yellow in color.
Explanation:
Working on number 7
Answer: 0.03798 kilograms
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 
of particles.
To calculate the moles, we use the equation:
1 mole of chlorine gas 
weighs = 71 g
Thus 0.535 moles of chlorine gas will weigh = 
(1kg=1000g)
Thus there are 0.03798 kilograms in 12 L of chlorine gas.
Answer:
It would become more neutral when diluted
Explanation:
Assuming you dilute it with water, the more diluted the substance, the more neutral (and closer to 7), it would be. Ie straight lemon juice is more acidic than lemonade, which is more acidic than water. I hope this helps :)
