6.349 g mass of anhydrous magnesium sulfate will remain.
<h3>What are moles?</h3>
A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Molar mass MgSO₄.7 H₂O = 246.52 g/mol
0.0527 moles
Molar mass MgSO₄ = 120.4 g/mol
Mass of anhydrous magnesium sulfate :
( 0.0527 x 120.4 ) => 6.349 g

Answer:heat-,7
Explanation:According to table P, heat- is an organic prefix used to represent 7 carbon atoms
Answer:
- <em>Brønsted-Lowry acid: HNO₂</em>
- <em>Brønsted-Lowry base: NH₃</em>
- <em>Conjugate acid: NH₄⁺</em>
- <em>Conjugate base: NO₂⁻</em>
Explanation:
The equation is:
<em>Brønsted-Lowry acids</em> are H⁺ donors.
<em>Brønsted-Lowry bases</em> are H⁺ acceptors.
Thus, on the left side, <em>HNO₂</em> is the acid and <em>NH₃ </em>is the base.
The <em>conjugate acids</em> and <em>conjugate bases</em> are on the right side of the equation.
The <em>conjugate acid</em> is the spieces that is formed after a base accepts the proton; thus it is <em>NH₄⁺</em>. A <em>conjugate acid</em> contains one more H atom and one more + charge than the base that formed it.
The <em>conjugate base</em> is the species that is formed after the acid donates its proton; thus, <em>NO₂⁻</em> is the <em>conjugate base</em>. A <em>conjugate base</em> contains one less H atom and one more - charge than the acid that formed it.
Summarizing:
- Brønsted-Lowry acid: HNO₂
