A geochemist in the field takes a 25.0 mL sample of water from a rock pool lined with crystals of a certain mineral compound X .

He notes the temperature of the pool, 15.° C , and caps the sample carefully. Back in the lab, the geochemist first dilutes the sample with distilled water to 450. mL . Then he filters it and evaporates all the water under vacuum. Crystals of X are left behind. The researcher washes, dries and weighs the crystals. They weigh 0.300 g . Using only the information above, can you calculate the solubility of X in water at 15.° C ? yesno If you said yes, calculate it. Be sure your answer has a unit symbol and 3 significant digits. ×10μ

Answer:

1- Yes, we can calculate the solubility of mineral compound X.

2- 0.012 g/mL.

Explanation:

<em>1- Using only the information above, can you calculate the solubility of X in water at 15.0 °C? </em>

The information available is:

The volume of water sample = 25.0 mL.

Weight of the mineral compound X after evaporation, drying, and washing = 0.30 g.

∴ Yes, we can calculate the solubility of mineral compound X.

<u><em>2-  If you said yes, calculate it.</em></u>

∵ 25.0 mL of water sample contains → 0.30 g of the mineral compound X.

∴ 1.0 mL  of water sample contains → ??? g of the mineral compound X.

1.0 ml of water sample will contain (0.3 g/25.0 mL) 0.012 g.

<em>∴ The solubility of the mineral compound X in the water sample is</em> <u><em>0.012 g/mL.</em></u>

<u><em></em></u>

Put the following in the correct chronological order from what happened first to what happened last.
Scilla [17]

Answer:

2-3-1-4

Explanation:

The astronomer Nicolaus Copernicus did not have a theory about the Earth revolving around the sun until he got into astronomy and began to study the patterns of the sun and the moon as well as reading other entries from previous astronomers. You can pretty much guess from there, he had to have the theory before proving it etc.

Calculate the density of a solid in g/cm3 if it weighs 38.3 kg and has a volume of 0.00463 m3.
RideAnS [48]

Answer: D=8.27 g/cm³

Explanation:

Density is mass/volume. Mass is in grams and volume is in liters. In this case, the problem wants our volume to be in cm³. All we need to do is to make some conversions to convert kg/m³ to g/cm³.

D=\frac{38.3kg}{0.00463m^3} *\frac{(1m)^3}{(100cm)^3} *\frac{1000g}{1kg}

With this equation, the m³ and kg cancel out, and we are left with g/cm³.

D=8.27 g/cm³

The nucleus of an element contains more protons then electrons.this is referred to a?
dedylja [7]

Answer:

ion

However atoms may gain or lose electrons in ordinary chemical reactions. If an atom has the same number of electrons as protons, it is a neutral atom. If it has a net charge, (more or less electrons than protons) it is an ion. If it has more electrons than protons it has a net negative charge and is known as an anion.
