I always do it and get it right
Answer:
There is no percent left for other foods
Explanation:
The total energy consumed was:
E = 2x1.2x10⁶ + 3x6.7x10⁵ =
E = 4.41x10⁶ J
Knowing that 1 cal = 4.184 J
1 cal --------- 4.184 J
y ---------------- 4.41x10⁶ J
By a simple direct three rule:
4.184y = 4.41x10⁶
y = 1.05x10⁶ cal
Which is higher than the 2000 calorie daily food intake, so there is no percent left for other foods.
False solutions are natural gas, nuclear power and industrial biomass incineration.
sugar in water is an example of true solution.
Answer:
D) 0.450 M
Explanation:
Given data
- Initial volume (V₁): 6.00 mL
- Initial concentration (C₁): 0.750 M
- Volume of water (VH₂O): 4.00 mL
- Final volume (V₂): V₁ + VH₂O = 6.00 mL + 4.00 mL = 10.0 mL
- Final concentration (C₂): ?
We can determine the final concentration using the dilution rule.
C₁ × V₁ = C₂ × V₂
C₂ = C₁ × V₁/V₂
C₂ = 0.750 M × 6.00 mL/10.0 mL
C₂ = 0.450 M
