What begins to happen to radioactive uranium as soon as a mineral containing it crystallizes from magma?

Chemistry

Aleonysh [2.5K]3 years ago

<span>The radioactive uranium decays into its daughter product, lead. It would do this in magma as well, as nuclear decay depends on forces within the atom, not on the phase of the material in which the atom is a part.</span>

Balance the following reaction: AL2O3 + HCI ⇒ ALCI3 + H2O
Anastaziya [24]
To balance the following chemical equation, make a tally or a count of each of the atoms on both sides of the reaction, and make sure that those atoms are equal on both the reactant and product side.

AL2O3 + HCl => ALCl3 + H2O

Left side. Right side
AL = 2. AL = 1
O = 3 Cl = 3
H = 1. H = 2
Cl = 1. O = 1

First balance the metal atoms, aluminum, then hydrogen and then oxygen.

Balanced equation :
AL2O3 + 6HCl => 2ALCl3 + 3H2O.

Left side. Right side
AL = 2 AL = 2
O = 3 Cl = 6
H = 6 H = 6
Cl = 6 O = 3.

Consider the following balanced equation:
algol [13]

Moles of PF₃ : 4

<h3>Further explanation</h3>

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

\tt P_4(s)+6F_2(g)\rightarrow 4PF_3(g)

1.25 moles of P₄(s) is reacted with 6 moles of F₂(g)

Limiting reactant : the smallest ratio (mol divide by coefficient)

P₄ : F₂ =

\tt \dfrac{1.25}{1}\div \dfrac{6}{6}=1.25\div 1\rightarrow F_2~limiting~reactant(smallest~ratio)

mol PF₃ based on mol of limiting reactant(F₂), so mol PF₃ :

\tt \dfrac{4}{6}\times 6~moles=4~moles

Let's consider a scenario in which the resting membrane potential changes from −70 mV to +70 mV, but the concentrations of all i
Inessa [10]

Answer: The correct answer is 1. outside and 2. inside.

Explanation:

During the resting potential (-70 mV), the concentration of Na+ is bigger outside than inside, so this situation generates a trend for moving inside. If we consider a scenario where the resting potential changes from -70 mV to +70 mV, we would realize that the electrical gradient would stop the entrance of Na+ ions and would make them to move outside.
