Answer:

250

Explanation:

all you have to do is divide them its simple division cause its by the volume by the density

Mass can be calculated by using moles which can be further calculated from multiplication of Molarity to volume. The mass of sugar to make this solution is  8.6 kg.

Molarity can be calculated by dividing  number of moles of solute by volume of solution in litre. Molarity is affected by temperature. Its unit is mole/litre. It measure the concentration of any solute in a solution.

Other concentration terms are molality, normality and mole fraction. Molarity can be used to find out the ionic strength of any solution

Mathematically,

Molarity= number of moles of solute/volume of solution in litre

Where,

moles= given weight /by molecular weight

         = w/ 96.0858

Substituting values in equation 1

0.6=(w/96.0858)/(150 )

w=8.6 kg

Thus the mass of sugar is 8.6 kg.

Explanation:

There is a trend in the periodic table.

I.E increases up the group and across the period. So you know that metals have less I.E compared to non-metals.

Answer:

The Law of Multiple Proportions explain that when two elements from a series of compounds, (replacing the two elements as A and B), the ratios of the masses of the second element that combine with 1 gram of the first element can always be reduced.

The answer the other guy gave is incorrect, and plagiarized.

My answer came from a lesson I learned.

Mass spectrometry is the technique that measures the ratio of mass to charge. The spectrum of the element Sb is most likely represented by 121 and 123 atomic mass. Thus, option B is correct.

Mass spectrometry plots the spectrum representing the ratio of mass-to-charge by the signals generated by the ions. The spectrum estimates the mass and isotopes of the sample elements. They also determine the chemical properties and structures.

The spectrometry detects the isotopes that are stable and are known to have the same atomic number. It can be used to determine the isotopes of an element based on their peaks generated on the mass spectrum. Antimony has two stable isotopes with atomic masses 121 and 123.

Therefore, option B. the spectrum of the element Sb is most likely represented by Sb-121 and Sb-123.

Explanation:

Answer:      The theory of plate tectonics tells us that the earth's surface sits on plates that shift due to the built up pressure underneath. When the pressure gets too much, it has to escape somewhere so it goes to the edges of the plate and causes earthquakes. This in turn causes the surface to shift.

Explanation:

Ionization Trend: First ionization energy will increase left to right across a period and increase bottom to top of a family (column).

If we compare Mg and Cl:

Mg is column 2 (far left) in the periodic table, while Cl is column 17 (far right). Based on the ionization rule explained above, Cl will have the higher first ionization energy.

Answer:

84.2 grams

Explanation:

you have to multiply 8.42x10^18 to get the answer above

The number of the atom can be used to estimate the mass and moles of the substance by Avogadro's number. The mass of 8.42 x 10¹⁸ atoms of Bromine is equivalent to 0.0011 grams.

The mole concept has been the unit of the amount of estimating the mass of the substances with smaller entities. It uses the SI unit mol to measure the amount of mass. It also has been defined by 6.02214076 × 10²³ (Nₐ, Avogadro's number) elementary entities.

The molar mass of  Bromine (Br) is 79.904 u and atoms are 8.42 x 10¹⁸.

Atoms to mass are converted as:

= ( 8.42 x 10¹⁸ atom ÷ 1 ) × ( 1 mole Br ÷ 6.02214076×10²³ ) × (79.904 gm Br ÷ 1 mol Br)

= (8.42 x 10¹⁸ × 79.904 gm) ÷ 6.02214076 × 10²³

= 6.727 × 10²⁰ ÷ 6.02214076 × 10²³

= 1.117 × 10⁻³ grams

Therefore, 0.0011 grams is the mass of bromine.

Tungsten's most common isotope will have the most quantitative effect on the average atomic mass.

The most common isotope of tungsten will represent its most abundant isotope.

The isotope with the most geonormal abundance will have the highest effect on the average atomic mass of an element.

Answer:

boron

Explanation:

boron has 5 protons and carbon has 6, so if carbon lost a proton, it would become boron since each element has a unique number of protons.

As each element has a different number of protons, boron has five and carbon has six, so if carbon lost one of its protons, it would change into boron.

Every atom has a proton, a subatomic particle, in its nucleus. The particle possesses an electrical charge that is positive and opposite to the electron's.

In the reaction, a proton is forfeited. Keep in mind that when the number of protons changes, the atomic number also changes, creating a new element. Carbon-14 is the end result as a result. It is a new element, yet it has the same mass as nitrogen-14.

When carbon creates covalent bonds, pairs of electrons are shared between the atoms instead of being gained or lost as happens with chemical bonds. The ability of carbon to construct lengthy chains of atoms and so create intricate biological compounds is due in part to this feature.

Thus, If carbon lost one proton, boron atom would be formed.

Explanation :

As we know that Mendeleev arranged the elements in horizontal rows and vertical columns of a table in order of their increasing relative atomic weights.

He placed the elements with similar nature in the same group.

According to the question, the atomic weight of iodine is less than the atomic weight of tellurium. So according to this, iodine should be placed before tellurium in Mendeleev's tables. But Mendeleev placed iodine after tellurium in his original periodic table.

However, iodine has similar chemical properties to chlorine and bromine. So, in order to make iodine queue up with chlorine and bromine in his periodic table, Mendeleev exchanged the positions of iodine and tellurium.

As we know that the positions of iodine and tellurium were reversed in Mendeleev's table because iodine has one naturally occurring isotope that is iodine-127  and tellurium isotopes are tellurium-128 and tellurium-130.

Due to high relative abundance of tellurium isotopes gives tellurium the greater relative atomic mass.
