C - In DNA, each base pairs up with only
one other base.
Pretty confident on this answers :D
Answer:
The chlorine gas and potassium bromide solution react to form liquid bromine and potassium chloride solution.
Explanation:
Chemical equation:
Cl₂(g) + KBr (aq) → KCl (aq) + Br₂(l)
Balanced chemical equation:
Cl₂(g) + 2KBr (aq) → 2KCl (aq) + Br₂(l)
This equation showed that the chlorine gas and potassium bromide solution react to form liquid bromine and potassium chloride solution.
Chlorine is more reactive than bromine it displace the bromine from potassium and form potassium chloride solution.
The given equation is balanced and completely hold the law of conservation of mass.
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
Aw, I hope I can help.
1) C
(A meter stick is the only form of measurement that measures distance)
2) C
(other metric units all correspond with other forms of measurement)
3/4) I can’t measure the line physically from my phone but I think you’d be alright!
5) B
(a triple beam balance measures mass!)
6) B
(corresponds with triple beam balance)
7) A: 34.5g B: 104.3g C: 132.5g
8) C
9) A
(a graduated cylinder is the only form of measurement that measures volume)
10) A
(corresponds with a graduated cylinder!)
An example of a dilute solution is tap water, which is mostly water (solvent), with a small amount of dissolved minerals and gasses (solutes). An example of a concentrated solution is 98 percent sulfuric acid (~18 M).
