Answer:
The final volume of NaOH solution is 30ml
Explanation:
We all know that
V1S1 = V2S2
or V1= V2S2÷S1
or V1= V2×S2×1/S1
or V1=100×0.15×1/0.50
V1= 30
∴30 ml NaOH solution is required to prepare 0.15 M from 100ml 0.50 M NaOH solution.
Answer:
1.3 L
Explanation:
The volume of a rectangular cube can be calculated using the following formula:
Volume (L) = length (cm) x width (cm) x height (cm)
Keep in mind that 1 L = 1,000 cm³.
Before you can plug the values into the equation, you need to make sure they all have the same unit. Since the length is in meters (m), you need to first convert it to centimeters.
1 meter = 100 cm
0.159 m 100 cm
--------------- x ---------------- = 15.9 cm
1 m
Now, you can solve for the volume. To find the answer is the unit liters, you need to divide the volume by 1,000.
Volume = l x w x h
Volume = 15.9 cm x 10.5 cm x 7.7 cm
Volume = 1,285.5 cm³
Volume = 1.2855 L ------> Volume = 1.3 L
The answer is C because it says describe the final sugar and C is unsaturated and in the problem it says as much as sugar will dissovle .
The products will be 
<h3>Chemical reactions</h3>
Zn is higher than hydrogen in the reactivity series. Thus, it will be able to displace hydrogen from the acid.
The equation of the reaction becomes: 
Hydrogen gas is released as a result. In fact, it is one of the ways of preparing hydrogen gas in the laboratory.

Answer:
Ionic bonds form between two or more atoms by the transfer of 1 or more electrons between atoms. Electron transfer produces negative ions called anions and positive ions called cations. ... In forming an chemical bond, the sodium atom, which is electropositive, loses its negatron to chlorine.
