The balanced equation of NaOH and H2SO4 would be:
2NaOH + H2SO4 = Na2SO4 + 2H2O
To determine the concentration of NaOH, we first find the moles of NaOH used in the reaction. We start with the the concentration and volume of H2SO4. We do as follows:
2.00 M H2SO4 ( 0.25 L ) = 0.5 mol H2SO4
0.5 mol H2SO4 ( 2 mol NaOH / 1 mol H2SO4) = 1 mol NaOH
Molarity = 1 mol NaOH / 2.00 L NaOH solution = 0.5 M NaOH solution
Ok so velocity is speed but includes direction. The formula for both speed velocity is distance over time. so the equation is 387 over 8.5. That equals 45.5294117647 which can be rounded to 46.
Answer:
The correct option is (d).
Explanation:
It is given that,
1$ = 1500 pesos
We need to convert 360 pesos into dimes
We can convert 360 pesos to dollars as follows:
360 pesos is equal to $0.24
Also, 1 dollar = 10 dimes
We can covert 0.24 dollar to dimes as follows :
0.24 dollar = 10 × 0.24 dimes
0.24 dollar = 2.4 dimes
or
360 pesos = 2.4 dimes
Answer:
1.006 * 103
Explanation:
Add the number between 1 and 9 and add a decimal accordingly . so the answer is 1.006 multiplied by 10 raised to power 3
Answer:
Ch4 + 2O2 ----> CO2 + 2H2O
Explanation:
Ch4 has 4H, 1C
O2 has 2 O2
CO2 has 1 C, 2O
H2O has 1 H, 2O
you need to add 2 to O2 to balance it. Add 2 to H2O to balance the H and O
