explain how to find the mass of water. show your calculations as well​

Answers

Answer 1

Answer:

You can find the mass of water by multiplying the density of water by its volume.

mass = Density x volume

Explanation:

It is very easy to find the mass of water once you know the formula of density. "Density" refers to mass per unit volume.

Density (ρ) = [tex]\frac{mass}{volume}[/tex]

Therefore, mass = ρ x volume

The density of water is 1 kg/L.

For example, if the volume of water is 500 ml, then you can get its mass by multiplying 500 ml by 1 kg/L.

Let's convert 500 ml to Liter first.

500 ml x [tex]\frac{1 L}{1,000 ml}[/tex] = 0.5 L

Now, let's compute.

mass = ρ x volume

mass = 1 kg/L x 0.5L

mass = 0.5 kg

The mass of a 500-ml water is 0.5 kg.

Based on the information in the table, which two elements are most likely in the same group, and why?

Answers

The answer would be Bismuth and Nitrogen because they have the same number of valence electrons. Groups in the periodic table are arranged in columns. When it comes to neutral atoms, the number of valence electrons it has is equal to the main group of that element.

What types of radiation cause the parent isotope to change into a different element?

Answers

Answer:

Beta decay is most common in elements with a high neutron to proton ratio. Gamma decay follows the form: In gamma emission, neither the atomic number or the mass number is changed. A high energy gamma ray is given off when the parent isotope falls into a lower energy state.

The praying mantis is a member of the Mantid group of insects. Mantids come in many shapes and sizes and are found all over the world. Some have patterns on their bodies that help them look like the ground. Some are bright green to blend in with leaves and plants. One special mantis is bright pink and looks like an orchid. The mantis is such a strange and engaging creature that many people keep them as pets. For many reasons, mantids have fascinated humans for many years.First, mantids show an amazing mastery of hunting skills. Mantids eat a wide variety of insects, including moths, crickets, bees, flies, grasshoppers, other mantids, and even, on occasion, small birds and snakes. They can capture prey many times larger than they are. Their powerful armor and amazing hunting skills make them quite effective. They have large powerful front legs, with spikes that help them hold on to prey. Their head can turn almost entirely around to follow prey without moving. Their front legs are so powerful and so fast that it is hard to see them move when capturing prey. One second their legs are empty and the next they are clutching tightly to something they have caught.Mantids are also stealthy. They wait, very still, very patiently for prey to come into sight. They also make slight swaying movements, to mimic leaves and grass moved by the wind. They focus intently on their victim. Then they pounce, suddenly, rarely missing their target. They are so successful they can triple in size every few months by molting when they outgrow their exoskeletons. They start out as nymphs, able to capture only prey that is smaller than they are. They end their lives about a year later becoming predators that can take down prey as large as hummingbirds.Finally, they are very personable, as far as insects go. They have a large, triangular-shaped head with large eyes. This alien-like appearance makes them quite cute. When you come across them in the garden, you can tell right away they are aware of you. They follow your movements as if to assess if you are either something to eat or something that will eat them. The little ones will accept rides on your finger if you are gentle. But be carefulthey can jump surprisingly far even when small. If they think your freckle is prey, you may be surprised to find a mantis on your nose.As far as predatory insects go, the mantis is one of the most impressive. Gardeners love to find them in on vegetables because mantids eat many insects that damage crops. However, they may also eat some insects that help a gardenerlike bees. Regardless, the mantis is a fascinating insect, and if you happen to see one hunting in the wild, consider yourself lucky.What quality makes mantids valuable to gardeners? The ability to eat a variety of insects The ability to be stealthy when hunting The quality of appearance and awareness The quality of their rapid growth Which percent is equivalent to 2.5?2.5%25%250%2,500% _______ are white blood cells that recognize specific antigens, and ultimately destroy them.O lymphocytesO pathogensO water Which sentence does the subject agree with the verb?

Gym has a reputation as most students' least favorite class. Fromchanging clothes twice in an hour to doing silly drills, the whole thing ispretty absurd. It makes no sense to insist that all students take gymclasses when everyone knows they are worthless. Today, there is lesstime than ever before devoted to regular school subjects like Englishand math. Instead of forcing students to spend time running around,schools should abolish gym and give the time back to academics. 9. Determine which of the following sequences is a geometric sequence.
