Volume of a rectangular block= 2.30x4.01x1.82=16.78cm3
Mass of the rectangular block= 25.71 g 
Density of the block will be = 25.71/16.78=1.53 g/cm3
So the 
ANSWER IS 1.53 g/cm3 density

  • Left to Right

<u>Chemistry</u>

<u>Atomic Structure</u>

  • Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.

<u>Stoichiometry</u>

  • Using Dimensional Analysis
<h3>Explanation:</h3>

<u>Step 1: Define</u>

1.2 × 10²⁴ molecules C₆H₁₂O₆ (glucose)

<u>Step 2: Identify Conversions</u>

Avogadro's Number

<u>Step 3: Convert</u>

  1. Set up:                               \displaystyle 1.2 \cdot 10^{24} \ molecules \ C_6H_{12}O_6(\frac{1 \ mol \ C_6H_{12}O_6}{6.022 \cdot 10^{23} \ molecules \ C_6H_{12}O_6})
  2. Divide:                                                                                                                      \displaystyle 1.99269 \ mol \ C_6H_{12}O_6

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 2 sig figs.</em>

1.99269 mol C₆H₁₂O₆ ≈ 2.0 mol C₆H₁₂O₆

Solid aluminum oxide and hydrogen gas are heated, molten aluminum and water vapor form?
ruslelena [56]

Answer:

No

Explanation:

The answer would be no.

<em>Solid aluminium oxide cannot react with hydrogen gas to produce molten aluminium and water due to the fact that, on one hand, hydrogen as an element is not a strong enough reducing agent that can remove oxygen from the aluminium oxide.  On the other hand, aluminium is more reactive than hydrogen and hence, cannot be displaced by hydrogen in solution.</em>

✞how are snythetic detergents better than soap??⭐⭐㋛​
iVinArrow [24]
Soaps work in soft water. However, they are not effective in hard water. In contrast, synthetic detergents work both in soft water and hard water. Therefore, synthetic detergents are better than soaps.
