Answers

Answer 1

Answer:

1272 pound

Explanation:

From the question given above, the following data were obtained:

Pressure (P) = 38 psi

Area (A) = 12 cm by 18 cm

Force (F) =?

Next, we shall determine the area. This can be obtained as follow:

Area (A) = 12 cm by 18 cm

A = 216 cm²

Next, we shall convert 216 cm² to square inch (in²). This can be obtained as follow:

1 cm² = 0.155 in²

Therefore,

216 cm² = 216 cm² × 0.155 in² / 1 cm

216 cm² = 33.48 in²

Finally, we shall determine the force exerted. This can be obtained as follow:

Pressure (P) = 38 psi = 38 lbf/in²

Area (A) = 33.48 in²

Force (F) =?

P = F/A

38 = F / 33.48

Cross multiply

F = 38 × 33.48

F = 1272 pound

Thus, the force exerted is 1272 pound

Why is it necessary to heat the hydrate gently at first and then more strongly only after most of the water has been driven off

Answers

Answer:

To avoid spattering

Explanation:

If we are heating a hydrate to drive off the water of crystallization, we must initially heat the hydrate gently, at a lower temperature and then more strongly only after most of the water has been driven off in order to to prevent spattering.

Since we obtain the amount of water by the mass difference, Spattering  decreases the mass of water obtained and ultimately results in a lower percent of water being calculated for the hydrate.

In the above figure, what type of bond is formed?



metallic


ionic


covalent


nonpolar

Answers

The answer is Ionic bond

Answer:

It is an covalent bond.

Explanation: The bond is covalent because all the dots are equaled to each other therefore creating a stable bond. When the bonded atoms have a lower total energy than that of widely separated atoms, a covalent bond forms. The electrons are not moved from one atom to the other in polar covalent bonds, such as that between hydrogen and oxygen atoms, as they are in an ionic bond.

During spontaneous fission, a nucleus of 25498Cf can produce 11846Pd, four neutrons, and what other nuclide?

Answers

Answer: 52Te - Tellurium

Explanation: Radioactivity occurs when an unstable nucleus of an element decompose into a stable element by emitting particles or forms of eletromagnetic energy. There are types of radioactivity and Spontaneous Fission is one of them.

In Spontaneous Fission, the unstable, also called parent, nucleus splits into two smaller nuclei and emitts one or more neutrons.

The reaction spontaneous fission of Cf is represented below.

25498Cf ⇒ 11846Pd + 4n + X

The characteristics of each element of the equation are:

1) The element Cf has atomic mass 254 and atomic number 98.

2) Element Pd has atomic mass 118 and atomic number 46.

3) Neutron is represented as n, has no atomic number and atomic mass 1.

Given these properties, to determine the other nuclide, we have to find out the nuclide's atomic number, as each element in the periodic table has its own atomic number.

At the left side of the equation, atomic number is 98. At the right side, element X's atomic number is

98 - 46 + 0 = 52

In the periodic table, the element with atomic number 52 is Tellurium, whose symbol is Te.

The other nuclide for the spontaneous fission is Tellurium (Te).

Calculate the number of moles in 19.3g of NaCl

Answers

Answer: 0.33 mole

Explanation:

Let the number of moles be represented by x.

We should note that 1 mole of NaCl = 58.44g

Therefore, the number of moles in 19.3g of NaCl will be :

= 19.3/58.44

= 0.33 mole

Therefore, the number of moles in 19.3g of NaCl is 0.33 mole

Answer:

I believe it’s C

Explanation:

I used Socratic and found a quizlet lol

The organism is reproducing asexually. Hence both offspring has the same number of genes and same traits.

What is asexual reproduction?

Asexual reproduction allows for the rapid production of vast numbers of children by a single person. Asexual reproduction is a successful method of reproduction in a stable or predictable environment since all the children will be suited to that environment.

Asexually reproducing organisms may be at a disadvantage in an unstable or unpredictable environment since all of the progeny are genetically similar and might not have the genetic diversity to survive in new or changing settings.

Therefore, the given diagram describes the reproduction of an organism by asexual method and giving offsprings of same number of genes and same traits. Hence, option C is correct.

How would the reactivity of an element with one valence electron vary from an element with 8 valence electrons

Answers

Answer:

An element with 1only one valence electron is extremely reactive while an element with 8 valence electrons is very stable and does not react most of the times

Explanation:

Valency is the number of electrons in the outermost shell of the atom. It shows the ease with which elements react and combine with each other.

An element can take a maximum of 8 electrons in most of its outermost shells. As a matter of fact, the goal for its stability is to attain a structure with all 8 slots for electrons in its outer shell filled up. The element can either do this by adding or removing electrons.

The ease with which it adds or removes the electrons shows its reactivity. If it has only one electron to lose, (the valence electron) the element will be very reactive because this is relatively easier to do when compared with 2 electrons, three electrons,  and so on. An element with 8 electrons in its outer shell is very stable and does not need to react anymore. an example of this is Neon and Argon.
