Answer:
Inertia
Explanation:
Inertia is the tendency of an object to resist a change in motion. Newton's First Law of Motion is also called the law of inertia. A full aquarium is harder to move than an empty one because the law of inertia.

The basis of the VSEPR model of molecular bonding is __________. Question 1 options: atomic orbitals of the bonding atoms must overlap for a bond to form regions of electron density in the valence shell of an atom will arrange themselves so as to maximize overlap electron domains in the valence shell of an atom will arrange themselves so as to minimize repulsions regions of electron density on an atom will organize themselves so as to maximize s-character Question 2 (1 point)
Answer:
Electron domains in the valence shell of an atom will arrange themselves so as to minimize repulsions
Explanation:
In accordance with VSEPR theory, the electron domains or electron pairs on the valence shell of the central atom in a molecule always position themselves as far apart in space as possible in order to minimize repulsions.
Recall that according to VSEPR theory, the shape of a molecule depends on the number of electron pairs or electron domains on the valence shell of the central atom of the molecule, both lone pairs and bond pairs. Lone pairs are known to cause more repulsions than bond pairs.
What happens when water turn’s into gas
Answer:
The process of turning water into gas is called evaporation. When water is heated, it changes state from a liquid to a solid. No mass is destroyed during the process, but rather, it is converted into gas.

Is this a scientific model? Use complete sentences to explain why or why not.
Answer:
its a scientific model
Explanation:
It is a scientific model because it is showing the water cycle. In the water cycle it is scientifically showing how water circulates through the Earth. For example, the water in the ocean evaporates which is evaporation, then it condensates into a cloud that then becomes condensation and the condensation makes precipitation when it rains. When it falls to the ground, it then becomes a runoff down a hill.

The molar mass of SO3 is grams.
Answer:
80.07 g/mol
Explanation:
Step 1: Define
Molar Mass S - 32.07 g/mol
Molar Mass O - 16.00 g/mol
Step 2: Find molar mass of compound
S = S × 1 = 32.07 g/mol
O₃ = O × 3 = 48.00 g/mol
32.07 + 48.00 = 80.07 g/mol

Identify each of the pictures as heterogeneous or homogeneous
Answer : The image C shows homogeneous mixture and image A, B and D shows heterogeneous mixture.
Explanation :
Heterogeneous mixtures : It is a mixture in which the constituent substances are not mixed well and do not have a uniform composition throughout the mixture that means appears non-uniformly throughout the solution.
Homogeneous mixtures : It is a mixture in which the constituent substances are mixed well and have a uniform composition throughout the mixture that means appears uniformly throughout the solution.
From the given image we conclude that the,
image C shows homogeneous mixture and image A, B and D shows heterogeneous mixture.

Most of the dissolved substance in sea water is: hydrogen chloride nitrogen sodium ANSWER NOW! I NEED HELP ASAP! WILL GIVE BRAINLIEST!
Answer: Sodium chloride
Explanation:
Ocean water contains a number of substances. When a substance which has ionic bonds is dissolved in water it takes the form of ions.
The most common ions in ocean water are sodium and chloride. These are the ions formed when common salt, sodium chloride (NaCl) is dissolved in water.
Sodium chloride accounts for about 3% of ocean water by mass.
Answer:
By far, the most abundant elements are hydrogen and water.
Explanation:
The analysis of the 77 sea water samples taken during the Challenger's 3-year voyage did much to lay the foundations for determining the chemical content of sea water. By far, the most abundant elements are hydrogen and water (combined to make water). Together, these elements make up 96% of sea water. Sodium chloride and magnesium make up just under 4% of sea water. Trace amounts of 97 other elements are found in the remaining 0.08%. Of the trace elements, calcium, potassium, sulfur, and bromine are the most abundant.

50. How many joules of heat must be absorbed by 0.375 kg of water to raise its temperature by 45.0 to 70.0°C. Specific heat of water is 4.184 J/gC or 1.0 cal/gC
51. What mass of water can be heated from 25.0 to 50.0°C by the adding of 2825 Joules?(Cp of H2O=4.184 J/g °C)
Answer:
50. 54,915 J
51. 27.0 g
Explanation:
The dimensional analysis tells you how to compute these. Multiplying specific heat, J/(g·°C), by the product of mass and temperature change will give you energy.
__
50. (375 g)((70 -45) °C)(4.184 J/(g·°C)) = 54,915 J
__
51. M((50 -25)°C)(4.184 J/(g·°C)) = 2825 J
M = 2825/104.6 g ≈ 27.0 g

composed of tellurium.
How many moles of Te are present in 100.00 g of the compound?
Answer:
The correct answer is 0.22 mol Te.
Explanation:
First, we have to calculate the mass of Te in the sample. We simply multiply the sample mass by the percentage of Te (28.53%= 28.53/100)
100.00 g x 28.53/100 = 28.53 g Te
The molar mass of Te is 127.60 g. Thus, the mass of 1 mol of Te is 127.60 g. With this, we calculate how many moles of Te there are in 28.53 g of Te:
28.53 g Te x 1 mol Te/127.60 g Te= 0.223 mol ≅ 0.22 mol
