Find the percent by mass concentration if the solution was prepared by dissolving 25.0 g of sugar into 100 g of water.

Answers

Answer:

25%

Explanation:

Percent by mass is looking at the percentage of mass within a a solution. So since there's 100g of water and 25 grams of sugar, you divide 25 by 100 to get the ratio. Then multiply by 100 to get the percentage.

How to add moisture to the air without a humidifier?

Answers

There are quite a few ways to add moisture into the air without a humidifier

A few things that can help add moisture are hanging your clothing to dry. hang drying your damp clothes will add moisture to the air over time as it evaporates and it will make your house smell like fresh clothes.

Another thing is a bath,  allow the water to cool off and leave the bathroom door open, the steam will add moisture to the air as the water cools.

This might seem silly but putting bowls or vases of water out on the windowsill on a sunny day mill moistens the air as it evaporates.

You can also get houseplants, moisture evaporates from the leaves and stems of plants. transpiration can help increase the humidity in your home.

What effect does salt have on a marshmallow?

Answers

Answer:

The original marshmallow was named for the inclusion of marshmallow root in the recipe. The roots and leaves of the marshmallow plant contain mucilage, a slimy-textured demulcent best known for its use as a homeopathic cough suppressant. Marshmallow root is considered to be soothing and mildly antimicrobial. It has long been used as an herbal treatment for minor digestive issues and skin irritations, although its use in the creation of its namesake confection has long since fallen by the wayside.

How did the industrial revolution contribute to global climate change

Answers

Answer:humans have put ridiculous amounts of carbon dioxide into the atmosphereThese events are linked to the mass burning of fossil fuels to meet an increase in human demand

So the answer is True

Explanation:

Burning fossil fuels, such as coal and oil, has increased the quantity of greenhouse gases in our atmosphere since the Industrial Revolution began around 1750.

What is atmosphere?

Atmosphere is defined as a layer of gas that surrounds a planet and is kept there by the gravitational pull of the planetary body. The atmosphere of Earth includes five primary layers and a number of minor ones.

Industrial revolution is defined as the transition of an economy based on agriculture and handicrafts to one driven by industry and machine production. The causes of industrial revolution are the advent of capitalism, European imperialism, efforts to mine coal, and the effects of the Agricultural Revolution are some of the factors that historians have recognized as contributing to the Industrial Revolution.

Thus, burning fossil fuels, such as coal and oil, has increased the quantity of greenhouse gases in our atmosphere since the Industrial Revolution began around 1750.

What is ionic salt ?

In chemistry, salt exists as a chemical compound consisting of an ionic group of positively charged cations and negatively charged anions, which results in a combination with no net electric charge. A common example stands table salt, with positively charged sodium ions and negatively charged chloride ions.

The fragment ions in a salt compound can be either inorganic, such as chloride (Cl−), or organic, such as acetate (CH3CO−2). Each ion can be either monatomic, such as fluoride (F−), or polyatomic, such as sulfate (SO2−4).

Just use the subscripts
You have 4 hydrogens in one NH4 compound, and you have 3 NH4, so that gives you 12 H and 3 N.
You also have a coefficient of 2 in front of (NH4)3, so that means you would multiply 12 H atoms by 2 and 3 N by 2, giving you 24 hydrogen atoms and 6 nitrogen atoms.
You also have 1 Phosphorus atom, and 4 oxygen atoms, so now add all your individual atoms up:

what volume will 28.0 g of O2 occupy at STP?

Answers

Considering the definition of STP conditions, 28 grams of O₂ will ocupy at STP 19.6 L.

The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

On the other side, the molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

In this case, you  have 28 g of O₂. The molar mass es 32 [tex]\frac{g}{mole}[/tex]

Next, you can apply the following rule of three: if 32 grams of the compound are contained in 1 mole, 28 grams are contained in how many moles?

[tex]number of moles=\frac{28 gramsx1 mole}{32 grams}[/tex]

number of moles= 0.875 moles

Now, you can apply the following rule of three: if by definition of STP conditions 1 mole of O₂ occupies a volume of 22.4 liters, 0.875 moles occupies how much volume?

[tex]volume=\frac{0.875 molesx22.4 L}{1 mole}[/tex]

volume= 19.6 L

Finally, 28 grams of O₂ will ocupy at STP 19.6 L.

Explain why reaction speed increases with temperature.

Answers

as the reaction speed involves the overcoming of the activation energy (due to a required amount of kinetic energy between the particles). When temperature is increased it will provide more energy for the movement of the particles to gain more kinetic energy meaning the rate at which the particles interact increase

How do catalysts generally affect chemical reactions? A They increase the temperature of the system. B They increase the surface area of the reactants. C They increase the activation energy by introducing enzymes. D They lower the activation energy by providing an alternate pathway.​

Answers

Answer:

D

Explanation:

A catalyst is a substance that increases the rate of a chemical reaction by lowering the activation energy without itself being consumed by the reaction.

Activation energy is the minimum amount of energy required for a chemical reaction to proceed in the forward direction.

A catalyst increases the reaction rate by providing an alternative pathway or mechanism for the reaction

Do you think the number of asteroid samples a pod is carrying could make a difference? Might that explain why the

unsure

Answers

How does weight affect the speed of an object? Mass doesn't affect speed directly. It determines how quickly an object can change speed (accelerate) under the action of a given force. Lighter objects need less time to change speed by a given amount under a given force.

https://www.mvorganizing.org/does-the-weight-of-a-car-affect-its-speed/

If a feather and a bowling ball were dropped in a vacuum(only gravity effects the variables), they will hit the ground at the same time. So if the mass keeps changing it, and the pod keeps stopping at different points it will take longer to accelerate or decelerate. I’m not totally sure, but here is an answer.

Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.

Group 18; The Noble Gases contains the elements on the periodic table that would be the least reactive out of all the elements. So, this include any gas element, such as helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og). Hence, if you have the options:
