melamori03 [73]

Answer:

D. liquid

Explanation:

Matter, which is any substance that has weight and occupies space, can exists in three states namely: solid, liquid and gaseous. In this question, water is being described as matter.

According to this question, a sample of water of volume 2litres is shaped like a cylinder in one container and shaped like a rectangle in another larger container. Based on this observation, the water sample is in a LIQUID STATE because a liquid has no indefinite shape but takes the shape of its container.

Hence, this water sample, takes the shape of its cylindrical container in the first scenario and shape of its rectangular container in the second scenario.

A lab team places 0.250g of an unknown solid acid in an Erlenmeyer flask. They neutralize the solid acid with 15.0ml of 0.210 M
Otrada [13]

Answer:

<u>Molar</u><u> </u><u>mass</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>unknown</u><u> </u><u>acid</u><u> </u><u>is</u><u> </u><u>7</u><u>9</u><u> </u><u>grams</u>

Explanation:

We have to first get moles in 15.0 ml of sodium hydroxide solution:

{ \sf{1 \: l \: of \:NaOH \: contains \: 0.210 \: moles }} \\ { \sf{0.015 \: l \: of \: NaOH \: contain \: (0.015 \times 0.210) \: moles }} \\  { \underline{ = 0.00315 \: moles \: of \: NaOH}}

since mole ratio of acid : base is 1 : 1, so;

moles of acid that reacted is <u>0</u><u>.</u><u>0</u><u>0</u><u>3</u><u>1</u><u>5</u><u> </u><u>m</u><u>o</u><u>l</u><u>e</u><u>s</u><u> </u><u>o</u><u>f</u><u> </u><u>t</u><u>h</u><u>e</u><u> </u><u>u</u><u>n</u><u>k</u><u>n</u><u>o</u><u>w</u><u>n</u><u> </u><u>a</u><u>c</u><u>i</u><u>d</u><u>.</u>

then we've to get molar mass:

{ \sf{0.00315 \: moles \: of \: acid \: weigh \: 0.250 \: g}} \\ { \sf{1 \: mole \: of \: acid \: weighs \: ( \frac{1 \times 0.250}{0.00315} ) \: g}} \\ { \underline{ = 79.4 \: g \approx79 \: grams}}
