⭐️The answer is ⭐️
As weight = mass × g so we have more weights on earth than on moon. Explanation: This is because gravitational force is immediately proportional to the mass of an object. Greater the mass, greater will be the gravitational force exerted by it and thus, more will be our weight
The reaction between the magnesium, Mg, and the hydrochloric acid, HCl is given in the equation below,
Mg + 2HCl --> H2 + MgCl2
The number of moles of HCl that is needed for the reaction is calculated below.
n = (0.4681 g Mg)(1 mol Mg/24.305 g Mg)(2 mol HCl/1 mol Mg)
n = 0.0385 mols HCl
From the given concentration, we calculate for the required volume.
V = 0.0385 mols HCl/(0.650 mols/L)
V = 0.05926 L or 59.26 mL
<em>Answer: 59.26 mL of HCl</em>
To express the answer of (6.93 x 10¹) (2.0 x 10-4) in scientific notation, it should be 1.4 x 10^-2. <span>To </span>multiply<span> two numbers expressed in </span>scientific notation<span>, simply </span>multiply<span> the numbers out front and add the exponents. I hope it helps. </span>
Gravitational, elastic, and chemical are three forms of potential energy.
