10 seconds = 8grams
then just divide by 2 another 4 times...
= 0.5grams after 50 seconds
In a single displacement / replacement reaction a single uncombined element replaces another element in a compound.
Single replacement is type of chemical reaction where an element react with a compound and take the place of another element in that compound.
example of this type of reaction is
Zn+ 2HCl -----> Zncl2 + H2
Answer:
Does lithium oxide react with hydrochloric acid?
Explanation:
Lithium Hydroxide reacts with acids to produce a Lithium salt: Hydrochloric Acid + Lithium Hydroxide → Lithium Chloride + Water. HCl + LiOH → LiCl + H2O. ... H2SO4 + 2LiOH → Li2SO4 + 2H2O
is this what you wanted to know?
The correct answer will be b
The volume of 6.00g iron is 0.762 cm^3.
<em>Step 1</em>. Calculate the <em>density of Fe</em>
The <em>specific gravity</em> (SG) of a substance is the ratio of its density to the density of water at 4 °C.
SG = density of substance/density of water.
∴ 7.87 = density of iron/1.00 g·cm^(-3)
Density of Fe = 7.87 × 1.00 g·cm^(-3) = 7.87 g·cm^(-3)
<em>Step 2</em>. Calculate the <em>mass of Fe</em>
Volume of Fe = 6.00 g Fe × (1 cm^3 Fe/7.87 g Fe) = <em>0.762 cm^3</em>
