Answer:

Number of moles = 0.87 mol

Explanation:

Given data:

Mass of calcium = 34.8 g

Number of moles = ?

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of calcium = 40 g/mol

By putting values,

Number of moles = 34.8 g/ 40 g/mol

Number of moles = 0.87 mol

Answer:

1.156x10²⁵ atoms and 4.8x10²⁴ atoms of oxygen

Explanation:

1 mole of a molecule X contains 6.022x10²³ molecules. In a molecules as H₂O, for example, there are 3 atoms (2 of H and 1 of O).

Thus, in 1 molecule of K₂SO₃ there are 6 atoms (2 of K, 1 of S, 3 of O). In 3.2 moles there are:

3.2mol K₂SO₃ * (6.022x10²³ molecules / 1mol) = 1.927x10²⁴ molecules.

The atoms are:

1.927x10²⁴ molecules * (6atoms / molecule) =

1.156x10²⁵ atoms

In 4 moles of oxygen, O₂, there are 2 atoms per molecule :

4mol * (6.022x10²³ molecules / mol) = 2.4x10²⁴ molecules * (2atom / molecule) =

4.8x10²⁴ atoms of oxygen

Answer:

d = 2.57456 g/cm³

Explanation:

Given data:

Length of metal bar = 853cm

Width = 24 cm

Height = 10 cm

Mass = 527064 g

Density of metal = ?

Solution:

Volume of metal bar:

Volume = length × width × height

Volume = 853 cm × 24 cm × 10 cm

Volume = 204720 cm³

Density:

d = m/v

d = 527064 g / 204720 cm³

d = 2.57456 g/cm³

Answer:

In each Amplify Science unit, students figure out

a phenomenon by asking questions, gathering

evidence, and coming up with an explanation of how

the phenomenon works. The Coherence Flowchart

visually represents the storyline of the unit, showing

the coherent flow of questions, evidence, and ideas that

support students as they build complex explanations

of the unit’s anchor phenomenon. The Coherence

Flowchart on the following pages (one chapter per

page) can be used to see the connections between

the questions that drive students’ experiences, the

evidence they gather, the ideas they figure out, and the

new questions that those ideas generate. The diagram

Explanation:

H₃O⁺ and H₂O .

H₂O + H⁺  ⇄   H₃O⁺

H₂O accepts proton to form H₃O⁺ so H₂O is base .

H₃O⁺  ⇄   H₂O + H⁺

Here H₃O⁺  is acid because it gives proton ( H⁺ ) .

HCO₃ ⁻ and H₂CO₃

H₂CO₃  ⇄   HCO₃ ⁻ + H⁺

H₂CO₃ is acid because it gives proton ( H⁺ )

HCO₃ ⁻ + H⁺ = H₂CO₃

HCO₃ ⁻  is base because it accepts proton .

Answer:

Explanation:

Correct order is as follows .

1 ) Determine the moles of each reactant present by dividing its mass by its molar mass

2 ) Determine the amount of product that could be formed from each reactant using the appropriate mole ratios.

3 ) Identify the limiting reactant as the reactant that produces the least amount of product.

4 )  To find the mass, multiply the number of moles of product formed (from the limiting reactant) by the molar mass of the product.

Answer:

D. The plates are different in size from the landmasses.

Explanation:

Answer:

An endothermic process is any process with an increase in the enthalpy H (or internal energy U) of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system. It may be a chemical process, such as dissolving ammonium nitrate in water, or a physical process, such as the melting of ice cubes.

Answer:

1.12M

Explanation:

Given parameters:

Volume of solution  = 2.5L

Mass of Calcium phosphate  = 600g

Unknown:

Concentration  = ?

Solution:

Concentration is the number of moles of solute in a particular solution.

Now, we find the number of moles of the calcium phosphate from the given mass;

        Formula of calcium phosphate  = Ca₃PO₄

         molar mass = 3(40) + 31 + 4(16) = 215g/mol  

Number of moles of  Ca₃PO₄  = [tex]\frac{600}{215}[/tex]   = 2.79moles

   Now;

  Concentration  = [tex]\frac{Number of moles }{volume }[/tex]  

 Concentration  = [tex]\frac{2.79}{2.5}[/tex]   = 1.12M

Geological activity determines geological structures. The prevalent types and forms of tectonic working in a place will control the form of structure that can be found in a terrain.

So, geologic activities controls the structure found in an area

Explanation:

We can describe electrons using four sets of quantum numbers;

principal quantum number (n)

orbital quantum number (l)

magnetic quantum number (ml)

spin quantum number (ms)

Since no two electrons in an atom can have the same value for all four quantum numbers according to Pauli exclusion theory, for the orbitals given one possible value for each quantum number is shown below;

For 1s-

n = 1, l= 0, ml = 0, ms= 1/2

For 2s-

n= 2, l =0, ml=0, ms=1/2

For 1s and 2s orbitals, there is only one possible value for ml which is zero.

Answer: The smallest bond angle in the molecule x-y-x is [tex]180^0[/tex]

Explanation:

According to VSEPR theory , each atom in a molecule will achieve a geometry that minimizes the repulsion between electrons in the valence shell of that atom.

In the given compound [tex]x-y-x[/tex], the number of electron pairs is 2 that means the hybridization will be [tex]sp^2[/tex]  and geometry of the molecule will be linear as there are two bond pairs .The bond angle for linear geometry is 180° which reduces the electron electron repulsions and maximise stability.

Answer:

An ocean current is a continuous, directed movement of seawater generated by forces acting upon this mean flow, such as breaking waves, wind, the Coriolis effect, cabbeling, and temperature and salinity differences. Features like depth contours, shoreline configurations, and interactions with other currents also influence an ocean current’s direction and strength. Ocean currents flow for great distances, and together, create the global conveyor belt that plays a dominant role in determining the climate of many of the Earth’s regions (illustrated in the NASA video below). For example, the Gulf Stream makes northwest Europe much more temperate than any other region at the same latitude. Another example is Lima, Peru where the climate is cooler than the tropical latitudes in which the area is located, due to the effect of the Humboldt Current.  Ocean modelling uses a mathematical model of the general circulation of an ocean, based on the Navier–Stokes equations on a rotating sphere with thermodynamic terms for various energy sources (radiation, latent heat). These equations are the basis for complex computer programs commonly used for simulating the atmosphere or ocean of the Earth.
