Answer:
47.5 mm are equal to 4.75 × 10⁻² m.
Explanation:
Meter and millimeter both are units of length. Millimeter is smaller unit while meter is larger unit. The one meter consist of thousand millimeter or we can say that one thousand millimeters are equal to one meter. In order to convert the meter value into millimeter we have to multiply the values with thousand.
we know that one meter is equal to 1000 millimeter.
1 m = 1000 mm
4.75 × 10⁻² × 1000 = 47.5 mm
47.5 mm are equal to 4.75 × 10⁻² m.
Answer:
Heat required = 1.23×10⁵J
Explanation:
Given:
Mass (m) = 500 gram
Specific heat = 6,090 J/g
heat of fusion = 247 J/g.
Find:
Heat required
Computation:
Heat required = 247 J/g× 500 g
Heat required = 1.23×10⁵J
Answer:
it the same side with the other side you fellow the other side
Explanation:
<span>The chemical equation for the Vinegar & Baking Soda reaction is:
NaHCO3(s) + CH3COOH(l) → CO2(g) + H2O(l) + Na+(aq) + CH3COO-(aq)
with s = solid, l = liquid, g = gas, aq = aqueous or in water solution
Another reaction is:
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2
The chemical reaction actually occurs in two steps.
First, there is double displacement reaction in which acetic acid in vinegar reacts with sodium bicarbonate to form sodium acetate and carbonic acid:
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2CO3
Then,Carbonic acid is unstable and undergoes a decomposition reaction to produce the carbon dioxide gas:
H2CO3 → H2O + CO2</span>
