Anxious-Ambivalent attachment is displayed when a child actively explores the environment but seeks out the caregiver for comfort or reassurance.  

• The form of attachment when children seem to distrust caregivers, and this insecurity usually signifies that their surroundings is explored with trepidation rather than excitement is known as Anxious-Ambivalent attachment.  

• In this form of attachment, children continuously look for approval from their caregivers and spontaneously observe their environments for fear of being abandoned.  

• The children developing under this form of attachment style, seem to carry what they have acquired into adulthood, and usually feel unloved by their partners.  

Thus, the given case is of Anxious-Ambivalent attachment.

Answer:

2.11x10^26 atoms in 350.8 moles of Aluminum

Explanation:

I converted moles to atoms by using Avogadro's number which is 6.022x10^23

The solution is:

350.8 moles of Al x (6.022x10^23/1 mole) = 2.11x10^26 atoms

Answer:

The correct answer is 4.5 g/mL.

Explanation:

To find the density, we must remember the formula for density, which is given by the following:

density = mass/volume

In this case, we are given both the mass and the volume, so we just need to plug in these values into the formula to solve for the density.  This is modeled below:

density = mass/volume

density = 2344 g/520 mL

density = 4.5 g/mL

Therefore, the correct answer is 4.5 g/mL (notice that the units for our answer match what is being asked for in the problem).

Hope this helps!

Answer:

Physical property

Explanation:

Physical properties differ from chemical properties in that a different substance is formed during a chemical process whereas, a physical property produces NO 'new' substance upon completion of change.  By definition, 'Triple Point' is the temperature-vapor pressure value where the substance of interest exists in all three states simultaneously; that is, solid, liquid and gas. In this, the chemistry of cyclohexane remains unchanged regardless of temperature-pressure conditions and no new compounds are formed as products of change.

Example:

At the triple point of cyclohexane C₆H₁₂(s)  ⇄  C₆H₁₂(l) ⇄ C₆H₁₂(g) ⇄ C₆H₁₂(s),  the cyclohexane is still cyclohexane regardless of state and is classified as a physical process. The combustion of cyclohexane in the presence of oxygen, however, produces new substances  (CO₂(g) and H₂O(g)) having chemical and physical properties different from original cyclohexane added in the process.

For the combustion of C₆H₁₂(g) => 2C₆H₁₂(g) + 13O₂(g) => 12CO₂(g) + 2H₂O(g) produces substances (CO₂(g) and H₂O(g)) having different physical and chemical properties than the C₆H₁₂(g) introduced into the system and is classified a chemical process.

Answer:

2.29 moles of SF₆ contain 334.5 g SF₆

Explanation:

Given data:

Mass of SF₆ = ?

Number of moles of SF₆ = 2.29 mol

Solution:

Formula:

Mass = number of moles × molar mass

Molar mass of SF₆ = 32.065 + (19)×6

Molar mass of SF₆ = 146.06 g/mol

Now we will put the values in formula.

Mass = 2.29 mol ×  146.06 g/mol

Mass = 334.5 g

2.29 moles of SF₆ contain 334.5 g SF₆ .

Answer:

option C is correct = 1.14 × 10²² molecules of  CO₂

Explanation:

Given data:

Number of moles of CO₂ = 0.0189 mol

Number of molecules = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

For given question:

1 mole of CO₂ =  6.022 × 10²³ molecules of  CO₂

0.0189 mol of CO₂ ×  6.022 × 10²³ molecules of  CO₂ / 1mol

1.14 × 10²² molecules of  CO₂

Thus, option C is correct.

Answer:

Empirical formula of compound  is C₄H₈O

Explanation:

Given data:

Mass of compound = 5.60 g

Mass of CO₂ = 13.7 g

Mass of H₂O = 5.60 g

Empirical formula of compound = ?

Solution:

Percentage of C:

13.7 g/5.60 g × 12/44× 100

2.45×0.273× 100 = 66.9%

Percentage of H:

5.60 g/ 5.60 g × 2.016/18 × 100

11.2%

Percentage of O:

(66.9% + 11.2%) - 100 = 21.9%

Grams atom of  C , H, O

66.9/12 = 5.6

11.2 / 1.008 = 11.11

21.9 / 16 = 1.4

Atomic ratio:

           C                 :               H           :              O

           5.6/1.4         :            11.11/1.4    :            1.4/1.4

              4                :               8            :               1

18.8 g Citric acid

Explanation:

We have a 5.00% (w/v) citric acid solution, that is, there are 5.00 grams of citric acid every 100.0 mL of the solution. We can use dimensional analysis to calculate the grams of citric acid in 375 mL of the 5.00% (w/v) solution.

375 mL Solution × (5.00 g Citric acid/100.0 mL Solution) = 18.8 g Citric acid

Answer:

31.31× 10²³ number of Cl⁻ are present in 2.6 moles of CaCl₂ .

Explanation:

Given data:

Number of moles of CaCl₂ = 2.6 mol

Number of Cl₂ ions = ?

Solution:

CaCl₂  → Ca²⁺ + 2Cl⁻

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

In one mole of CaCl₂ there are two moles of chloride ions present.

In 2.6 mol:

2.6×2 = 5.2 moles

1 mole Cl⁻ =   6.022 × 10²³ number of Cl⁻ ions

5.2 mol ×  6.022 × 10²³ number of Cl⁻  / 1mol

31.31× 10²³ number of Cl⁻
