which compound contains both ionic and covalent bonds

Answers

Answer:

Any compound that contains a metal ion and a polyatomic ion would work. Polyatomic ions are covalently bonded non-metals that have some overall charge. Examples of common polyatomic ions include OH⁻ (hydroxide), NH₄⁺ (ammonium), and NO₃⁻ (nitrate). So answers to this question can be something like KOH (potassium hydroxide), but really, anything works if it contains a metal ion and a polyatomic ion.

why does hydrogen fluoride have a high boiling point

Answers

The intermolecular bonding for HF is van der Waals, whereas for HCL, the intermolecular bonding is hydrogen. Since the van der Waals bond is stronger than hydrogen, HF will have a higher boiling temperature. Since the covalent bond is stronger than van der Waals, HF will have a higher boiling temperature.

Why are cloudy nights warmer than clear nights?​

Answers

Clouds are a source of Infrared Radiation. When cloud coverage increases, the infrared radiation also increases. So the clouds basically act as space heaters. This emits energy towards the ground, which is what makes cloudy nights warmer. While with clear sky’s all the heat from the day just escapes back into the atmosphere so the temperatures will be colder.

What percentage of the Periodic Table of Elements is Metals?

Answers

80 percent

About 80 percent of the elements are metals (shiny elements that conduct heat and electricity well), and 15 percent of the elements are nonmetals (poor conductors of heat and electricity). The remaining elements are metalloids, which share properties of both metals and nonmetals.

Which elements are the most reactive and why?

Answers

Answer:

Fluorine is identified as the most reactive nonmetal and the most electro-negative element in the periodic table, making it the strongest oxidizing agent. Caesium is the most reactive metal in the periodic table, so much that working with this metal often ends in explosions!

Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.

Hope that helps.

Alkali metals (situated far away from transitional metals and noble gases) are the most reactive elemental group. Cesium is second from the bottom of this group, with 6 electron shells, so it fits all the characteristics of a reactive atom, therefore making it the most reactive element.

the actual yield is i believe 20.03g
i may be wrong and if i am, i am extremely sorry and also sleep deprived

Answer:

20.03g

Explanation:

This is the formula for percentage yield:

Percentage yield = Actual Yield / Theoretical yield

Rearrange it to get the Actual yield, which would be:

Actual yield = Percentage yield (in decimal form) x Theoretical yield

We know that 75% of CO2 is produced as the percentage yield in a reaction and the theoretical yield for the mass we're supposed to find is 26.7 grams.

Percentage yield in decimal form: 0.75

Theoretical yield: 26.7g

Plug it in the equation

Actual yield = 0.75 x 26.7g

Actual yield = 20.03g

Oxygen and fluorine are the two elements that have more protons per atom than the element phosphorus.

What is phosphorus?

Phosphorus (P), a nonmetallic chemical element of something like the nitrogen group (Group 15 [Va] of the periodic table), is a colorless, semitransparent, soft, sticky solid that glows in the dark at room temperature.

Hennig Brand, a German businessman with an interest in alchemy, appears to have discovered phosphorus around 1669. Brand left 50 buckets of pee alone till they putrified and "produced worms." He then reduced the urine to a paste and burned it with sand to extract elemental phosphorus first from combination.  Oxygen and fluorine are the two elements that have more protons per atom than phosphorus.

Therefore, oxygen and fluorine are the two elements that have more protons per atom than phosphorus.

what you know about the
properties of acids and bases,
which would you expect from
vinegar?
A. It should feel slippery.
B. It will release OH-in water.
C. It will release H+ in water.

Answers

Answer:

C

Explanation:

Acids contain H plus ions. When within a solution or neutralised these ions are released.

The substance which gives H+ ion are called as acid. Vinegar is an acid because it will release H+ in water. Therefore, option C is correct.

What is vinegar ?

Acetic acid and water are combined to create vinegar through a two-step fermentation process. First, yeast consume any liquid derived from a plant source, such as fruits, whole grains, potatoes, or rice, and feed on the sugar or starch therein. It ferments into alcohol.

White vinegar typically contains 93–96% water and 4-7% acetic acid. It can be used to cook, bake, clean, and control weeds. It may also help with weight loss and decrease cholesterol and blood sugar levels.

The sugar is converted to ethanol (ethyl alcohol) by yeast and bacteria in a two-step fermentation process, which is followed by the production of acetic acid. Vinegar is acidic because it contains acetic acid.

Thus, option C is correct.

for the reaction 2nh3(g)↽−−⇀ 3h2(g)+n2(g), if 15.8 grams of ammonia produced 1.87g of hydrogen, what was the percent yield

Answers

Answer:

75%

Explanation:

So, the reaction will consume 1 mole of hydrogen gas and produce

1mole H2⋅2 moles NH33moles H2=0.667 moles NH3

at 100% yield. This represents the reaction's theoretical yield.

Now, you know that the reaction produced 0.50 moles of ammonia. This represents the reaction's actual yield.

In order to find the percent yield, you need to figure out how many moles of ammonia are actually produced for every 100 moles of ammonia that could theoretically be produced.

You know that 0.667 moles will produce 0.50 moles, so you can say that

100moles NH3.in theory⋅0.50 moles NH3.actual0.667moles NH3.in theory=75 moles NH3.actual

Therefore, you can say that the reaction has a percent yield equal to

% yield = 75%
