Explanation:
as the ionic compound decreases in size, the melting point __
A. increases
B. decreases
c stays the same
Answer:
A. increase
Explanation:
the smaller the size of the ionic compounds, the more closer they get packed together. This means electrostatic attraction also increases, which means the ionic bonds gets stronger...therefore increases the melting point

b is answer
Explanation:
please follow me
Answer:
B is the answer
Explanation:
A is incorrect as there is 2 O2 on the RHS while there is only 1 O2 on one side
B is correct as it is going through a process called combustion and I don't feel like explaining it is too long T^T
C is incorrect as the 3 results in multiply N (3 Nitrogen) while there is only one N2
D is definitely incorrect -.-
Hope this helps

napthalene combustion can be used to calibrate the heat capacity of a bomb calorimeter The heat of combustion of naphthalene is -40.1kj/g. When .8210g of naphthalene was burned in a calorimeter containing 1,000g of water, a temperature rise of 4.21C was observed. What is the heat capacity?
A bomb calorimeter with a heat capacity of 3.63 kJ/°C experiences a temperature rise of 4.21 °C when .8210 g of naphthalene is burned.
The combustion of naphthalene is used to calibrate the heat capacity of a bomb calorimeter.
What is a bomb calorimeter?It is a device used to measure the change in the internal energy of a reaction.
To determine the heat capacity of the calorimeter (C), we need to follow a series of steps.
Step 1: Calculate the heat released by the combustion.The heat of combustion of naphthalene is -40.1kJ/g and .8210g were burned.
Qcomb = -40.1kJ/g × .8210g = -32.9 kJ
Step 2: Determine the heat absorbed by the bomb calorimeter.According to the law of conservation of energy, the sum of the heat released by the combustion and the heat absorbed by the bomb calorimeter is zero.
Qcomb + Qbomb = 0
Qbomb = -Qcomb = 32.9 kJ
Step 3: Calculate the heat capacity of the bomb calorimeter.32.9 kJ were absorbed, part by the calorimeter itself and part by the 1,000 g (m) of water, whose specific heat capacity (c) is 4.18 J/g°C.
A temperature rise (ΔT) of 4.21 °C is observed. We can determine the heat capacity of the bomb calorimeter (C) using the following expression.
Qbomb = Qcal + Qwater
32.9 kJ = C × ΔT + c × m × ΔT
32.9 kJ = C × 4.21 °C + (4.18 × 10⁻³ kJ/g.°C) × 1,000 g × 4.21 °C
C = 3.63 kJ/°C
A bomb calorimeter with a heat capacity of 3.63 kJ/°C experiences a temperature rise of 4.21 °C when .8210 g of naphthalene is burned.

How many teaspoons are equal to 1 mole of water if there is 0.23 teaspoon for every 1 g?
A. 0.46 teaspoon
B. 3.68 teaspoons
C. 4.14 teaspoons
D. 18 teaspoons
Answer:it's b hope that help
The molar mass of water is 18 g. Given that there are 0.23 teaspoon for every 1 g. Thus , for 18 g there would be 4.14 teaspoons.
What is one mole?Any substance that contains 6.022 × 10²³ number of atoms is called one mole of that substance. The mass of a compound or molecule containing these much atoms is called its molar mass.
Molar mass of water is 18 g. Thus, it means that one mole of water weighs 18 g. Given that for every 1 g of water there are 0.23 teaspoon. Thus, number of teaspoons for one mole or 18 g of water is:
number of teaspoons = 18 g × 0.23 /1 g
= 4.14 teaspoons.
Therefore, 4.14 teaspoons are required for one mole of water.

The value of probability density will be
The probability density function is nonnegative everywhere, and its integral over the entire space is equal to the terms "probability distribution function" and "probability function" .
What is probability density function?
In probability theory, a probability density function (PDF), or density of a continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the random variable would be equal to that sample.
Probability density is the probability per unit length, in other words, while the absolute likelihood for a continuous random variable to take on any particular value is 0 (since there is an infinite set of possible values to begin with), the value of the PDF at two different samples can be used to infer, in any particular draw of the random variable, how much more likely it is that the random variable would be close to one sample compared to the other sample.

Answer:
C
Explanation:
Answer:
c
Explanation:
Venus and Earth are often called twins because they are similar in size, mass, density, composition and gravity. Venus is actually only a little bit smaller than our home planet, with a mass about 80% of Earth's.
1. Which of the following shows the process of freezing?'
A.candle wax cooling on the table
B.pouring cola over ice
C. heating a cup of water
D. particles are speeding-up and colliding more
Answer:
A. candle wax cooling on the table
Explanation:
Candle wax cooling on a table is an example of freezing because the atoms in the candle wax start to slow down as the wax cools. This is considered "freezing" because the slower an atom is vibrating then the colder it is and of course the faster an atom is vibrating then the hotter it is! :)

How many valence electrons does the following isotope have?
Answer:
I have solution to your question
Nitrogen is 7th element in periodic table. It contains 7 electrons in which are 2 are inner electrons and 5 are outer electrons. Here N is in -3 oxidation state. Thus, it is having 8 valence electrons.
What is an isotopes?Isotopes of are atoms with same atomic number and different mass numbers. Almost every elements have isotopes but some of them are unstable in nature.
Atoms forms ions when they lose or gain electrons. Wen they lose electrons, they form positive ions called cations. When they gain electrons they form negative ions or anions.
Nitrogen is 7th element in periodic table. It has 7 electrons out which 2 are inner electrons and 5 are valence electrons. N needs 3 more electrons to attain octet. Thus it gains 3 electrons and forms its 3 - oxidation state.
Thus N in -3 oxidation state have 8 valence electrons.
