\text{Hey there!}

\text{Vanessa jogged 8 miles in 2 hours. What was her average speed?}

\text{First,, highlight/ underline your key-terms. Then solve it from there!}

\text{Key term  1: \underline{8 miles}}\\\text{Key term 2: \underline{ in 2 hours}}

\text{Now we have to find her average speed. }

\text{Formula: }\dfrac{\text{a}}{\text{b}}

\text{a = 8}\\\text{b = 2}

\dfrac{8}{2}= \text{the answer}\\\\\dfrac{8\div2}{2\div2}=\dfrac{4}{1}= 4\\\\\\\boxed{\boxed{\bf{Answer: 4}}}\checkmark

\text{Good luck on your assignment and enjoy your day!}\\\\\frak{LoveYourselfFirst:)}

Addition of 6 m hcl to which substance will not result in gas evolution?
saul85 [17]

There is no gaseous product when NaNO3 reacts with 6M HCl.

We must note that gas evolution is one of the signs that a chemical reaction has taken place. Hence, we must consider the options and look out for an option in which reaction with HCl does not lead to a gaseous product. This is the option that does not lead to evolution of a gas.

Let us consider the reaction; NaNO3(s) + HCl(aq) ---> NaCl(s) + HNO3(aq), there is no gaseous product hence NaNO3 does not result in gas evolution upon addition of 6M HCl.

Missing parts;

(C) K2CO3

(D) NaNO3

10 moles of hydrogen are allowded to react with 6 moles of oxygen .How much water molecules are obtained?
DiKsa [7]

Answer:

Since 2H₂ + O₂ ---> 2H₂O

We need 2 moles of hydrogen for each mole of oxygen

So, we need 2(6) = 12 moles of H₂ but since we only have 10 moles,

H₂ is the limiting reagent

So since 2 moles of H₂ gives 2 moles of water,

10 moles of H₂ will give rise to 10 moles of Water with 1 mole of remaining oxygen
