Answer: it is a cation (a positively charged ion). its charge is (+). It will have one positive charge.

Explanation: Ions are charged atoms. Ions can be positively charged or negatively charged. A positively charged ion is called a cation while a negatively charged ion is called an anion. Cation is formed when an atom loses one or more electrons while an anion is formed when an atom gains one or more electrons. Normally, an atom has no charge that is, it is neutral because an atom always have equal number of protons and electrons. Protons have positive charge while electrons have negative charge. For instance when atom which have 8 electrons and 8 protons loses one electron, it will then have 7 electrons and 8 protons, thereby making the atom to have a positive (+) charge.

A student needs to prepare 250 mL of a 0.550 M aqueous solution of sucrose, C 12 H 22 O 11 ( aq ) , which is used frequently in
Grace [21]

Answer:

Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.

Explanation:

You need to prepare 250. mL of a 0.550 M aqueous solution of sucrose, C12H22O11 (aq),

which is used frequently in biological experiments.

Based on your answer above, what is the value of x?

Solution:

A 0.550 M aqueous solution contains 0.550 mole of sucrose per liter of solution.

250 ml = 0.250 liter

Thus a 0.250 liter of a 0.550 M aqueous solution of sucrose contains 0.250 * 0.550 = 0.1375 mole of sucrose

Recall:

Mass = number of moles * mass of 1 mole

mass of 1 mole of C12H22O11

= 12(12) + 1(22) + 16(11)

= 144 + 22 + 176

= 342 grams

Mass = 0.1375 * 342 = 47.025 grams of sucrose.

Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.

AfilCa [17]
<span>The theory puts forward the concept that chloroplasts were developed from one form of prokaryotic organisms taken up inside a primordial eukaryotic cell. This is an organism form that uses light energy to divide, this part of its processes became the chloropplast whilst another formed the origin of mitochondria.</span>

Imagine you are an engineer who needs to test a scale model of a
FinnZ [79.3K]

Answer:

The problem will be because:

  • <u>The error in the construction of the bridge will be actually 40 cm</u>.

Explanation:

When you, as an engineer, listen about a scale 1/20, it means that for each 1 cm in the model, it will be 20 cm in the real footbridge (20 times upper to the scale model), then how the error in the model is 2 cm, the real error is 40 cm, in this case, imagine that you didn't know that the bridge will have an error of 40 cm, which is approximately 1,31 ft, <em><u>from a side of the bridge you begin with the correct measure, and the other side you use the measure with the error of the 40 cm, the result is that when you going to finish the bridge in the center, this won't match, making more expenses to correct that big error</u></em>.
