Answer:

56.5J

Explanation:

<em>To </em><em>find</em><em> </em><em>the </em><em>heat </em><em>energy</em><em> </em><em>required</em><em> </em><em>use </em><em>the </em><em>formula</em><em> </em><em>for </em><em>the </em><em>specific</em><em> </em><em>heat </em><em>capacity</em><em> </em><em>which </em><em>is </em>

<em>c=</em><em>quantity</em><em> of</em><em> </em><em>heat/</em><em>mass×</em><em>c</em><em>h</em><em>a</em><em>n</em><em>g</em><em>e</em><em> </em><em>in </em><em>temperature</em>

<em>in </em><em>this </em><em>question</em><em> </em><em>c </em><em>is </em><em>0</em><em>.</em><em>2</em><em>2</em><em>6</em><em>j</em><em>/</em><em>g,</em><em>the </em><em>mass </em><em>is </em><em>5</em><em>0</em><em>g</em><em> </em><em>and </em><em>the </em><em>change </em><em>in </em><em>temperature</em><em> </em><em>is </em><em>3</em><em>0</em><em>-</em><em>2</em><em>5</em><em>=</em><em>5</em>

<em>therefore</em>

<em>0</em><em>.</em><em>2</em><em>2</em><em>6</em><em>=</em><em>Q/</em><em>5</em><em>0</em><em>×</em><em>5</em>

<em>Q=</em><em>0</em><em>.</em><em>2</em><em>2</em><em>6</em><em>×</em><em>2</em><em>5</em><em>0</em>

<em> </em><em> </em><em> </em><em>=</em><em>56.5J</em>

<em>I </em><em>hope </em><em>this</em><em> helps</em>

Consider the following reaction. Zn(s) 2agno3(aq) --&gt; 2ag(s) zn(no3)2(aq)when 16. 2 g of silver was produced, _____ mole(s) o
Crazy boy [7]

The required amount of silver nitrate to produce 16.2g of silver is 25.48 grams.

<h3>What is the relation between mass & moles?</h3>

Relation between the mass and moles of any substance will be represented as:

n = W/M, where

  • W = given mass
  • M = molar mass

Moles of silver = 16.2g / 107.8g/mol = 0.15mol

From the stoichiometry of the given reaction it is clear that, same moles of silver nitrate is required to produce same moles of silver. So 0.15 moles of silver nitrate is required.

Mass of silver nitrate = (0.15mol)(169.87g/mol) = 25.48g

Hence required mass of silver nitrate is 25.48g.

Lead will float in water.
Fed [463]

Actually, no. While their mass may be the same (1kg), the volume of lead is a lot smaller than that of feathers. As there is the same mass stuffed in a smaller space, it must be denser. The density of water is 1 g/cm3, so if the density of the lead is more than 1g/cm3, it has to sink

To answer this question, you may need access to the periodic table of elements.
OleMash [197]

Answer:

b.) Br and Br

Explanation:

A covalent bond occurs when electrons are shared between two atoms causing them to form a bond.

A "pure" covalent bond refers to a nonpolar covalent bond. In these bonds, the electrons are shared equally between two atoms as a result of the absence of an (or very small) electronegativity difference. The purest covalent bond would therefore be between two atoms of the same electronegativity. Two bromines (Br) have the same electronegativity, thus making it the purest covalent bond.

Polar covalent bonds occur when electrons are shared unequally between two atoms. There is a larger electronegativity difference between the two atoms, but not large enough to classify the bonds as ionic. In this case, a.) and c.) are polar covalent bonds and d.) is an ionic bond.

What is the bond between Ca and Cl
gtnhenbr [62]

ionic bond is formed between ca and cl forming molecule cacl2 ca has 2 velancy and cl has one velancy (ca has 2 electrons in its outer most shell while cl has 1 electron vecancy in its outermost shell). So ca would make bond with 2 cl atoms
